Maize leaf spot disease: Generally, the amount of rainfall in July is proportional to the incidence of small spot disease. When the diseased plant rate is 100%%, and the diseased leaf rate is 30%%, it will happen even in rainy weather. Remove 1~2 diseased leaves at the bottom of the corn and destroy them; spray 50% carbendazim or 70% thiophanate 500 times, or mancozeb 800 times, or 50%% fenoxacin 500 times etc. .
Maize big spot disease: Select the local planting varieties and the growing corn field. Take five sampling points. When the diseased plant rate reaches 100%% and the diseased leaf rate reaches 30%%, there will be a rainfall process and the disease can be controlled. Can be sprayed with 12%% green milk copper, or 25%% of the enemy off 2000 times, or 40%% of Weiwei suspoemulsion 1000 times or 80%% of the new Wansheng 700 times.
Corn round spot disease: Select disease-sensitive varieties, take five sampling points, check 10 strains at each point, and generally spray control at the height of the fruiting period, with 25%% triadimefon 500--800 times liquid.
Corn smut: The disease should be removed promptly.
Maize virus disease: There is corn rough shrinkage and dwarf mosaic disease (flower mosaic streak disease), and the degree of occurrence of corn virus disease can be judged according to the occurrence degree of wheat bush dwarf disease. The prevention and control are mainly to eliminate weeds and pests. In the field investigation, suspicious diseased plants were found and should be removed immediately and sprayed with anti-virus agents. For example, 25% of the virus a-500 times, or 5% of the bactericidal agent + Tianfengsu + zinc fertilizer, or 25% of the virus, etc. .
Corn borer: pay attention to hatching progress of eggs and larvae damage in the field, and seize the key period to prevent and control granules in the first generation of corn mash. It can be made into granules with bt emulsion or granules made of 1605, phoxim EC or granules of Beauveria bassiana, or 3% of Lehr granules, or 98% of Bataan soluble powder. In the corn big bell, kill the newly hatched larvae.
Corn Moth: Mainly harmful to the corn field. In the second half of July, when 500 eggs were found to have 2 eggs, or when the ear of the bitten grains reached 15% or more, they were immediately controlled. Corn silking can be organized to manually catch insects, or spray control.
