Disease Prevention and Control Techniques of Melon and Solanaceous and Vegetable Crops

Melon and Solanaceous crops, including watermelon, bitter gourd, chayote, pumpkin, tomato, eggplant, pepper, strawberry, etc., have been cultivated in the country for over a thousand years. Watermelon and melon are crisp and juicy, sweet and delicious. It is important in summer. Refreshing summer, fitness and good products; cucumber, bitter gourd and other rich in protein and vitamins, after eating can not only increase appetite, help digestion, but also medicinal value. Tomatoes, eggplants, peppers and other rich in vitamins and trace elements, become the best dish. With the improvement of people’s living standards, people’s demand for melon products is getting higher and higher. In the past, these products were not seen in the winter and spring seasons due to the constraints of climate conditions and restrictions on cultivation techniques. In order to continuously improve people’s living standards and meet market demands, governments at all levels will vigorously introduce and popularize advanced cultivation techniques such as greenhouse planting, protected land cultivation, three-dimensional planting, intensive production, and off-season sales, as well as market development, to fundamentally solve people’s problems. The long-standing difficulties in the demand for vegetable baskets have also played an important role in the development of the rural economy and accelerating the peasants' ability to lift themselves out of poverty. The cultivation of melons and solanaceous vegetables is not an easy task from planting to harvesting, especially for off-season planting, three-dimensional planting and intensification, and the development of greenhouse vegetables, providing conditions for cross-infection of diseases in recent years. Melon and eggplant vegetable crops have a trend of development. If it is not controlled in time, it will reduce production, reduce quality, and reduce farmers' income. How to prevent these diseases? Jinghan Active Kang Zhuangfeng Group has specially produced a scientific and technological CD-ROM for disease prevention and control of cucurbits and solanaceous vegetables for reference by the majority of farmers in the production process: different growth of melons, solanaceous and vegetable crops throughout the growing period During the period, there are more than 30 kinds of common diseases, difficult diseases, three-dimensional diseases and cross diseases. These diseases are caused mainly by fungi, bacteria, viruses, nematodes and physiological diseases: The main diseases caused by fungi are: Fusarium wilt: At the beginning of the disease, the melon leaves gradually wilted from the back to the front, appearing to be lack of water, especially at noon, but recoverable sooner or later. After 3-6 days, the whole leaf withered and drooped, unable to recover, and the outer base of the stem was easy to shrink. A brown spot or amber gel appears in the diseased area. The roots turn brown and rot, and the base of the stem is longitudinally split. When the humidity is high, pink mildew develops on the surface of the diseased area. 2. Broom disease: It mainly infects stem vines and also invades leaves and fruits. Leaf lesions appear round or irregular shaped dark brown lesions, small black spots on the lesions; melanocarpus infections are near grey and white oval irregular lesions. Spots on the small black spots. In the early stages of the disease, water-stained lesions developed, and the central area became brown. The dead spots were star-shaped and cracked. The interior was cork-like dry rot and rotted after being slightly dark. 3, anthrax, leaves and melons suffer heavy damage, the edge of diseased leaves first appeared round or semi-circular brown or dark brown lesions, the outer periphery often has yellow-brown halo. There are black spots or pale red sticky spots on the leaves. The base of the stem near the ground became dark brown, and petiole and melon vines were infected with water and immersed in yellowish round spots, which were slightly sunken and later turned black. 4. Epidemics: Seedlings and adult plants can be affected. After the cotyledon is infected, the first light greenish circular spots appear as water-soaked, and the center gradually turns reddish-brown. It is easy to shrink or die near the ground. True leaf disease at the beginning of the disease, students dark green, immersed round, or no plastic lesions, rapid expansion, when the humidity is rotten, like boiling water burned. After the light brown easily broken. Stem base infected with imitation hammer-shaped water-immersed dark green depression spot. Surrounding the base was completely rotted, and all of the affected area died. The fruit is infected with dark greenish-green water-soaked depression spots, and the whole fruit is quickly expanded. (5, leaf blight: also known as brown spot disease occurs in every growth period of watermelon. Cotyledon disease is mostly in the edge of the water have water spots, after turning into a light brown to brown round or semicircular Water stain spots, high humidity, extended to the entire cotyledon after dry; true leaf disease, in the back of the leaf, leaf margins or veins between the obvious water spots small spots, humidity caused by dehydration leaves blue and dry. High temperature, easy to form 2-3 mm round, near-round brown spots, covered with foliage, and then fused into a large spot, the disease department becomes thin, the formation of leaf blight. Stem vine disease formed spindle-shaped or slightly concave oval Brown spot. Fruits infected with a brownish brown spot on the fruit that grows slightly around the fruit and can penetrate deeper into the flesh, causing flesh to rot. When the humidity is high, the disease minister produces a gray layer of black mold.) 5. Tomato rot: fruits Brown round lesions, slightly sag, later on the formation of concentric patterns on the lesions, dense black spots. The disease department is more solid and does not soften and rot. There are cucumber downy mildew, gray mold, sclerotia, black spot disease, etc.; watermelon disease, anthrax, etc.; melon leaf blight, damping-off disease; tomato's early and late blight, Mianbing disease, Gray mold, Phytophthora blight, spot blight, etc.; eggplant Verticillium wilt disease, brown streaky disease, brown star disease, etc.; pepper scab, anthrax, brown spot disease and so on. The main diseases caused by bacteria: 1. Bacterial angular spot, (Cucumber 14'25) Keratopathy mainly damages the leaves and also harms the fruits. In severe cases, the leaves die and the fruit decays. After infesting the leaves, small spots of water-stained spots initially appeared on the leaves, which then expanded. Due to the limitation of the veins, a polygonal yellow-brown lesion was formed. There were oily-like pathogens around the lesions. This is a different condition from downy mildew. When wet, white bacteria on the back of the leaf sac, lesions easily cracked or perforation-like, fruit lesions also appeared after the water-stained lesions, the surface of white bacteria sac. Severe onset of warm, rainy, wet, low phlegm, and heavy phlegm. 2. Tomato bacterial wilt: The symptoms of the common damaged plants are obvious at the seedling stage. The symptoms are: the top leaves droop, then the lower leaves wither, the epidermis of the main stem of the diseased plants is rough, adventitious roots, adventitious buds are proliferated, the ducts turn brown, and there are pyoderma. Overflowing, the disease returned to normal in the early morning, but the catheter was blocked soon after the disease became infected, and the diseased plant died of blight. 3 Tomato canker disease: The disease is caused by vascular bundle disease caused by bacteria, resulting in wilting or death of plants in seedlings or fruit setting stages. At the beginning, the lower leaves wilted and droop, and the leaves curl up and resemble a lack of water. When bacteria reach the tip, sometimes One or a portion of the leaflets withered and the rest of the leaves were normal, with narrow and long strips appearing on the stems later and extending upwards and downwards, and the pith was browned up to one or more sections. After the pathogenic bacteria invade the fruits through vascular bundles, the fruits shrink, deformity, diapause, and seeds cannot mature. Freckled white round dots often appear on the fruit and turn brown afterwards. The center is slightly rough and the lesion is white halo around the lesion. 4 Soft rot of hot peppers: Occurs in the wounds and is initially stained with water, dark green, rot and dry, withered white, and pepper scab. Major diseases caused by viruses: There are three types of common tomato virus diseases: Mosaic type: Caused by tobacco mosaic virus. On the leaves there appeared yellow-green interphase, dark and light, and transparent veins. The leaves were slightly wrinkled and abnormal. Generally, the diseased plants were healthier and the plants were slightly shorter. Fern leaf type: mostly caused by cucumber mosaic disease. The plants showed different degrees of dwarfing. All or part of the upper leaves began to become thread-filled, and the middle and lower leaves began to become linear in whole or in part. The middle and lower leaves were slightly revolved, and the corolla thickened and increased to form giant flowers. Stripe type: Caused by mixed infection of tobacco mosaic virus and cucumber mosaic virus or 1-2 viruses, and the disease develops under high temperature and strong light conditions. Stained leaves, vines and fruits are dark brown at the beginning. The shape of lesions often varies depending on the site of disease. The leaves are mostly brown-brown spots or moire, and vines form brown patches of various shapes. However, the discolored part is located in the epidermis and does not penetrate into the stem or fruit. Watermelon virus disease: different pathogens, different onset period, the symptoms are quite different, but in any case, all show growth inhibition, often mottled or green patches on the leaves, the sooner the victim is, the heavier the incidence, the fruit is often damaged Or loss of green. (215"-3'30) Cucumber virus disease is also caused by virus infection, and its main transmission medium is cotton aphid and peach aphid (also known as cucumber mosaic disease, which is a disease that impregnates the entire living system. After infection, the plants up to the new leaves, down to the roots, each part of the cucumber is accompanied by a virus, the leaves show different shades of burn spots after infection; or yellow and green leaves, leaves often uneven, diseased leaves Smaller, severe leaf rewinding, the lower leaves of the plant gradually become yellow and die, the stems and vines of the diseased plants are shortened internodes, not melon, often die due to atrophy, and yellow and green and white patches are produced after infection of the melon strips. Uneven, malformed.) The main diseases caused by pests are: common root-knot nematode disease of cucumber, root-knot nematode disease of eggplant, etc., mainly endangering the roots, lateral roots, or fibrous roots. , size, etc.. Anatomical root knots, the disease organization has a small milky white nematode.The above-ground part of the plant showed a weak growth, which affected the fruitfulness, and the severe leaves were scattered, causing death.The above diseases, in addition to virus disease from the cotton aphid, Tao Ye In the case of aphid transmission, nematodes are caused by nematodes, and others are caused by soil borne bacteria, seed bacteria, and the spread of water currents and air currents.For the above transmission routes, active and robust bacteria, bactericidal bacteria, chlorella, kecine, and bacteria are used. , Sterilization 99, special effects bacteria killing, Miao Kangzhuang, speed of Kang, extinction Fengjing Khan active Kang Zhuangfeng series products, according to the flexible use of the characteristics of the series of products, can take soil treatment, seed dressing, seed soaking when transplanting Roots, stems, leaves, roots, sprinkling, tube roots, tubers, fruit fumigation, fruit tree holes, etc. The new type of pesticides, active and healthy, can rejuvenate the dead plants, regenerate diseased plants, and weaken The rejuvenation strain has one drug, multiple effects, and six functions: a disease prevention and treatment, a root strengthening strain, a stress resilience, a flower and fruit protection, an increase in yield, and a premature increase in income. In particular, according to the outstanding advantages of active, healthy, broad-spectrum, high-efficiency, internal absorption, green, and non-resistance, combined with pathogenic transmission routes and production conditions, you can adopt soil disinfection, foliar spray and soaking, seed dressing and dipping. Root, Irrigation, Splash , fruit fumigation, stem coating and hole injection and other methods to prevent and cure various diseases First, the soil treatment can kill the bacteria in a certain range of soil. Before the seedlings are sprayed with the soil table with live Kang Zhuang 3000-5000 times, and then 2. When the seeds are treated and the seedlings are transplanted, the rooting of the liquid can kill the germs in the soil around the seeds and seeds, and the germs around the roots of the seedlings, so as to ensure rapid emergence, emergence, and seedling growth. Before germination, soaking with live Kangzhuang 6000-8000 times for 4-12 hours, or rooting for 10-20 minutes when transplanting.. 3. Foliage spraying is the use of active and robust systemic action, the liquid in the plant Up and down the conduction to reach the site of the disease to kill bacteria.In the early stage of disease, spray the foliar and disease parts with active Kangzhuang 5000-8000 times.The severe disease field, serious diseased plants spray once again in 7-10 days.Drought days and root diseases should be combined with irrigation. Root, 0.5-1 kg of liquid per plant Fourth, for viral diseases, should be killed before the prevention and treatment of cotton aphid, or in the prevention and treatment of pests should also be added to spray a certain amount of pesticides. 5. During production, prevention and control shall be carried out by eliminating the sources of overwintering, cultivating strong seedlings, strengthening field management, selecting disease-resistant varieties, and prevention-oriented principles. Sixth, because the crops have more diseases during the growth, they can also be sprayed with active and healthy Zhuang in each growth period. This will not only reduce the investment, but also ensure that the plants are protected from diseases and thrive. Active and healthy have a broad spectrum, high efficiency, internal absorption, no resistance characteristics. Its broad-spectrum nature means that it can both kill fungi, kill bacteria, and kill viruses; the systemic absorption ensures that any part of a crop comes into contact with the liquid and it quickly conducts germs in the plants; The resistance guarantees that the product is used repeatedly during the growth period of the crop, and the efficacy is consistent; efficiently guarantees a good control effect with a small amount of liquid; plus this product has a multi-effect, a six-function In the prevention and treatment of diseases, it also has the effect of strengthening, resisting, and increasing production. It can also cause weak seedlings, young and old seedlings, crackers, malformed fruits, and three falling diseases caused by physiological diseases such as salt and alkali and low temperature. To better control effect. The use of this product can be mixed with the remaining acidic pesticides, and synergies, mixed with foliar fertilizer can accelerate the absorption of the liquid. The new pesticide active Kangzhuang was developed by the national scientific and technical personnel based on ion resonance and stereochemistry theory and advanced biochemical technology for crop physiology and pathogenic texture. Used everywhere, the effect is magical. The masses claimed that they could resurrect the "dead" strain, rehabilitate the diseased plant, rejuvenate the weak strain, and indeed be a treasure for harvest. Active Kang Zhuang Feng got its name. This product has been registered in the National Bureau of Industry and Commerce and won the 2002 National Patent Expo Gold Award. It is the only high-tech product that promises an invalid refund. Please ask your farmer friend to use it with confidence. You will surely get a satisfactory return!
