Cowpea pest control method

Abstract

The invention discloses a cowpea pest control method. The method comprises the steps of planting soil selection, improved variety selection, sowing treatment, seedling raising period management, plantadjustment, pruning and pinching, water and fertilizer management, pest control, agricultural control, medicament control, harvesting and seed reservation. According to the method, a 225-fold water solution of 1% Wuyi glucine wettable powder or a 1200-fold solution of 10% difenoconazole WG is uniformly sprayed in a field to achieve the optimal effect of preventing and treating powdery mildew andgray mold, and meanwhile, a greenhouse is built on the field, and the temperature in the greenhouse is controlled to be 18-23 DEG C, so that cowpea planting is facilitated, and braconidae is suitablefor survival. According to the method, cowpea leaves can be used for providing certain nutrition for reproduction of the braconidae while insect pests such as etiella zinckenella and American leaf miner are prevented and treated through the braconidae, so that a favorable prevention and treatment effect on cowpea insect pests is achieved, the braconidae is bred, and remarkable economic benefits and social benefits are obtained.

Description

technical field [0001] The invention relates to the field of prevention and control of vegetable diseases and insect pests, in particular to a method for preventing and controlling cowpea diseases and insect pests. Background technique [0002] Cowpea is an annual twining, herbaceous vine or nearly erect herbaceous plant of the family Fabaceae and Vigna genus, sometimes with twining tops, nearly glabrous stems, pinnate compound stipules lanceolate, with lines; Pointy, glabrous, racemes axillary, with long stalks; flowers clustered at the top of the inflorescence, often with fleshy glands between pedicels; calyx light green, bell-shaped, flag petals oblate, wing petals slightly triangular, keels Petals slightly curved; ovary linear, hairy, pod drooping, erect or slanted, linear, slightly fleshy and swollen or firm, with many seeds; seeds oblong or cylindrical or slightly reniform, yellow-white, dark red or other colors, cowpea is eaten with tender pods.

Problems solved by technology

[0003] At present, when it is used in practice, cowpea has a large planting area in my country, a wide range, and many varieties. However, there are many major diseases and insect pests of cowpea. If it is not handled and treated in time, it will directly cause the yield of cowpea to decline. It will waste energy and time, and also cause economic losses. The traditional planting method has a high incidence of diseases and insect pests. The common main diseases include root-knot nematode, powdery mildew, mosaic virus disease and bacterial blight, etc. The main pests are pods. Borer, thrips, Liriomyza sativae and whitefly, etc. In order to suppress cowpea pests and diseases, vegetable farmers often blindly use pesticides methamidophos, parathion, methyl parathion, carbofuran, omethoate, fenvalerate , cyhalothrin, cypermethrin, triazophos, acephate and triadimefon, etc., have gone to the other extreme, causing the pesticide residues in cowpea to exceed the standard, and there have been food safety problems for vegetables, so that people talk about cowpea. , dare not rest assured to eat
