Peanut Root Rot Control

Symptoms are commonly known as "rat tail" and rot. Each growth period can be disease. Infected just germinated seeds, causing bad seeds; seedlings were injured, the main roots became brown and the plants withered. Plants were affected. There were concave brown spots on the roots of the main roots. The roots were wet and rot. The cortex was brown and rot. It was easily detached and detached. There were no lateral roots or very few. Roots and necks are adventitious when wet. The upper part of the diseased plant is short, poorly growing, the leaves turn yellow, the flowering results are few, and most of them are pods.

The pathogen Fusarium solani (Mart.) Sacc. called Fusarium solani, F. oxysporum Schlecht. Fusarium oxysporum, F. roseum (Lik) S. et H. F. rosaryi, F. tricinctum (Corde) Sacc. F. moniliforme Sheld. called F. moniliforme Sheld. Fusarium spp. and other five kinds of Fusarium can cause disease, are all fungi of the subphylum Fungi. Both produce microspores, megaspores, and chlamydospores. Microspores are colorless, cylindrical, many single cells, size 5-122-3.5 (μm). Megasporate sickle or crescent, with 3-5 divisions. The chlamydospores are solitary or clustered, nearly spherical, 7-11 μm in size. In addition, it is thought that F. solani (Martias) App. et Wr. var. martii (App. et Wr.) Wr. f. 3 Snyder said F. graminearum type C is also the cause of the disease.

Transmission routes and pathogenic conditions The pathogens overwintered in soil, diseased bodies and seeds and became the source of infestation early in the year. The pathogens mainly spread through rainwater and agricultural operations and directly invade from wounds or epidermis, and the diseased plants produce conidia for reinfection. Seedlings are often overcast and heavy with heavy humidity. Continuous cropping, shallow soil, and sandy lands are susceptible to disease.

Prevention methods (1) rotation. The sick field is in every year round, and the sick field rounds for 3-5 years. (2) Deep plowing and soil improvement, organic fertilizer application, rational drainage and irrigation, and enhancement of disease resistance. (3) Strict seed selection, elimination of sick and weak seeds, seed dressing with 1% seed weight of 50% bacteriophage wettable powder. If necessary, spray or root the root rot 300 times.

Ginseng can improve the general condition of diabetic patients, but does not change the degree of hyperglycemia. In other words, ginseng can reduce urinary sugar and blood sugar in patients with mild diabetes mellitus by 40-50 mg, which can be maintained for more than two weeks after discontinuation of medication. Although the effect of reducing blood sugar in moderate diabetes mellitus patients is not obvious, most of the general conditions have improved, such as thirst disappeared or alleviated; some patients can reduce insulin consumption after taking ginseng.
