Wheat seedlings pay attention to pests and diseases

Under normal circumstances, about 15 days after the sowing of wheat, the wheat seedlings are basically the same, and various diseases have begun to occur one after another. The following methods are recommended to prevent and treat diseases and pests of wheat seedlings.

McMug: In addition to the wheat yield loss caused by direct damage, wheat stubble can also spread wheat yellow dwarf disease. When the planting rate exceeds 5% and 100 plantings are about 10, chemical control should be carried out. Use 25 ml per acre net or 20 grams of a large heroin or 20 grams of imidacloprid to spray 40 to 50 kg of water, and can be used to treat wheat spider mites.

Underground pests: The underground pests that injure wheat during the seedling stage are earthworms, cockroaches, and wireworms. According to observations, when maggots were harmed, the young seedlings of the young wheat seedlings were bitten into a mess and the fractures were not neat; when the crickets were damaged, the roots of the young wheat seedlings were snapped and the fractures were neat; the golden needle was eaten to eat the stems of the wheat, and the affected part was in a mess. But the skin is still connected. By carefully observing the damages of the wheat seedlings, it is possible to determine what kind of underground pests the wheat field has emerged. Sprinkle poisonous soil: Use 2% methyl isophorus powder per acre to mix 30 to 40 kilograms of finely ground soil. Mix well and apply to a wheat ridge in a ditch, which can effectively control the damage of earthworms and golden needles. Sprinkling irrigation solution: For plots damaged by spotting, 40% methyl isothiophosate or 50% phoxim 0.5% water for 60-75 kg water can be used per acre. Worms have special effects.

Aphids and cockroaches: In recent years, the occurrence of these two types of pests has been very large, often causing early seedlings of wheat seedlings. It can use 90% crystals of trichlorfon 75 grams per acre, first open with hot water and add water to 1.5 kilograms. Crush the sauteed wheat bran 5 to 7 kilograms, dubbed the bait, seduce and kill along the ridge, the effect is very good.
