Wheat rust wheat 15 to 20 days after emergence, select wheat field for investigation, when the disease leaf rate reaches 10%, and the autumn temperature is high, the rain is too much, immediately spray leaf rust or powder rust 1000 times liquid for prevention and treatment; Spray with 50% fresh urine or 3% ammonium sulfate water, also has a certain effect.
Wheat total etch disease The pathogen of wheat total rot disease can be infested in autumn seedling stage, and it is the peak of infection 20 to 30 days after emergence. For the plots where total erosion has occurred in the past, 120% to 200g of rusting emulsifiable concentrate per acre, 50-60kg of water, and seedlings sprayed along the ridge can significantly reduce the incidence of wheat spikes.
Wheat sheath blight Wheat sheath blight can occur from autumn seedling stage to heading stage. The symptoms in the seedling stage are mainly in the underground part. After the emergence, the underground stems of the wheat are damaged, which makes it brown, and develops upward. Many elliptical lesions are formed on the leaf tips of the base 1~2, and the residual dimension after the lesions decay Tube bundle tissue can cause dead seedlings in severe cases. For severely affected plots, use 150% of rusting emulsifiable concentrate per acre, or 150 to 200 grams of 5% jinggangmycin, or 50 to 75 grams of carbendazim WP, 50 to 75 kg of water. Spraying along the ridge, the effect is good.
In addition to directly reducing the yield of wheat, the aphid can also transmit wheat yellow dwarf disease. When the rate of sputum is more than 5% and the amount of sputum is about 10, the drug should be controlled. The method is: using 40% omethoate emulsifiable concentrate of 1000-1500 times of liquid per acre, or 1500 times of 5% times of long-acting phosphorus emulsifiable concentrate, the effect is very good, and can simultaneously treat wheat red spider.
There are three kinds of underground pests: cockroach, cockroach and golden worm. Select a representative plot survey, when the dead seedling rate reaches 3%, immediately apply the drug control.
1 Poisoning soil. 2 kg of 5% phoxim granules per acre, or 3 to 4 kg of 3% phoxim granules, or 2 kg of 2% methyl isoflavin powder, 30 to 40 kg of fine soil, mix well and then open Ditch application, or spreading along the ridge and then raking the soil, can effectively control cockroaches and golden worms.
2 pouring water. 40 kg of methyl isoflavone or 50% phoxim emulsifiable concentrate per acre is 0.5 kg, and water is 750 kg. It is applied along the ridge and has special effects on alfalfa and golden worm.
3 scatter bait. Use wheat bran or cake powder 5 kg, stir fry, add appropriate amount of water and 50% methyl isoflavin or 50% 1605 emulsifiable concentrate 50g, mix well and sprinkle in the field in the evening, 2 to 3 kg per acre, confrontation The control effect can reach more than 90%.
