The sowing period of wheat is a key period for preventing and treating various pests and weeds of wheat. During this period, the prevention and control of labor, time, and medicine can be controlled, and various pests and diseases can be controlled, and the results are more effective. According to the incidence of wheat diseases and insect pests in our county, the main control targets for pests and diseases in wheat sowing period are underground pests, cockroaches, cockroaches, golden needleworms, wheat midge insects, wheat sheath blight, total erosion disease, virus disease, yellow dwarfism, and smut. Its prevention measures are:
I. Selection of disease-resistant pests The selection of disease-resistant pests for the major pests and diseases in the region, and the rational distribution of varieties.
Second, create disease-prevention ecological environment, fine soil preparation, clearing the field of sickness and weeds. Rational rotation, formula fertilization, application of mature farmyard fertilizer. Adopting suitable cultivation methods, such as adequate planting in late planting and precision semi-precision sowing, the resistance of wheat itself to pests and diseases is improved, which is not conducive to the occurrence of diseases and insect pests, and is conducive to the healthy ecological environment of wheat.
Third, the treatment of soil insect pest wheat midge replant area, per acre can be used 50% phoxim or 40% methyl isophosphorus EC 0.25 ~ 0.3 kg, add 1 ~ 2 kg of water, 25 kg of fine soil made of toxic soil. You can also use 3% methyl isofluosal or phoxim granules 2.5 to 3 kg, 15 to 20 kg of fine soil, evenly spread the ground before plowing, and plow the soil into the soil.
Fourth, pesticide seed dressing for the general area of ​​the ground pests, available 40% methyl isophosphorus or 50% phoxim 0.05 kg, add 4 to 5 kg of water, mixed with wheat seed 40 to 50 kg. Rhizoctonia solani, smut, stripe rust, 2% rickettsin can be used according to species weight 0.1% to 0.15%, or 12.5% ​​pod fruit (carbenol) seed weight 0.12% seed dressing. The excessive use of pods has an impact on the emergence and growth of wheat, and it is necessary to strictly control the dosage. Full wheat rot disease can be used when the 2.5% Coke 100 ml, add 1.5 to 2 kg of water, mixed with 50 to 100 kg of wheat seed, sowing after drying. In the mixed area of ​​pests and diseases, we must vigorously promote the mixed dressing of fungicides and insecticides, and calculate the amount of each, first mix the insecticide and then mix the bactericide, and strictly follow the seed dressing operation procedures to prevent poisoning of humans and animals.
Fifth, the use of coated seed Seed coating has the advantages of simple, sustained release, long-term, etc. In addition to pest control, some coating agents also have the role of seed fertilizer, should be widely promoted. According to the types of diseases and insect pests, the appropriate formulations of seed coating agents can be selected. Such as using 2.5% Siyue seed coating agent plus 40% of methylisophos-methyl, it can prevent and control underground pests, but also can prevent wheat sheath blight, root rot and so on.
