Pollution-free medicament for prevention and treatment of sclerotium disease of cowpeas

Abstract

In summer, diseases of cowpeas are very liable to induced due to the hot and humid weather; and for prevention and treatment, a common method is spraying a pesticide, but the cowpeas need to be picked every day once podding period starts; what is more, it is unable to separate the pods from the plants during spraying the pesticide, so that it certainly causes high pesticide residue on the cowpeas on market. The invention provides a pollution-free medicament for prevention and treatment of sclerotium disease of the cowpeas and aims to the sclerotium disease of the cowpeas during picking period. In 100 kg of water, 0.5-2 kg of wood vinegar and 0.3-0.5 kg of 2% Wuyimycin aqueous solution are added to prepare a diluent, which is then used for spraying application on infected cowpea plants comprehensively. The medicament can rapidly treat the diseases of the cowpeas without residue of any harmful substances, thereby satisfying production demands on standards of green foods and organic foods.

Description

technical field [0001] The invention belongs to the technical field of cowpea cultivation, in particular to a method for safely preventing and treating cowpea diseases by spraying wood vinegar and wuyienin dilution prepared in a certain proportion and concentration. Background technique [0002] Cowpea is native to the tropical regions of India and Myanmar. It likes to be warm in nature, and the optimum temperature for growth is 20-25°C. The high temperature and high humidity in summer can easily induce cowpea diseases, and the conventional control method is to spray pesticides. Once the cowpea starts to set pods, it has to be picked every day, otherwise the commodity value will be reduced. The serious problem is that it is impossible to separate the fruit from the plant when spraying pesticides. There is also the case of spraying pesticides in the morning and picking in the afternoon, which will inevitably lead to high pesticide residues when cowpeas are on the market. Wi...

Problems solved by technology

Once the cowpea starts to set pods, it has to be picked every day, otherwise the commodity value will be reduced. The serious problem is that it is impossible to separate the fruit from the plant when spraying pesticides. There is also the case of spraying pesticides in the morning and picking them in the afternoon, which will inevitably lead to high pesticide residues when cowpeas are on the market.

With the increasing resistance of diseases to conventional pesticides, the dosage of pesticides sprayed by vegetable growers is increasing, so that the food safety of cowpea on the market is becoming more and more problematic
