Pollution-free medicament for prevention and treatment of powdery mildew of cucumbers

Abstract

In summer, diseases of cucumbers 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 cucumbers need to be picked every day once the fruiting period starts; what is more, it is unable to separate the fruits from the plants during spraying the pesticide, so that it certainly causes high pesticide residue on the cucumbers on market. The invention provides a pollution-free medicament for prevention and treatment of powdery mildew of the cucumbers and aims to the powdery mildew of the cucumbers during picking period. In 100 kg of water, 0.5-2 kg of wood vinegar and 0.1-0.5 kg of 4% agricultural antibiotic 120 are added to prepare a diluent, which is then used for spraying application on infected cucumber plants comprehensively. The medicament can rapidly treat the diseases of the cucumbers 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 cucumber cultivation, and in particular relates to a method for safely preventing and controlling cucumber diseases by spraying wood vinegar prepared at a certain ratio and concentration and Nongkang 120 dilution. Background technique [0002] Cucumbers are native to the tropical regions of India and Myanmar. They like to be warm in nature, and they are not resistant to cold or heat. The high temperature and high humidity weather in summer can easily induce cucumber diseases, and the conventional control method is to spray pesticides. Once cucumbers start to fruit, they have to be picked every day, otherwise the value of the commodity 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...

Problems solved by technology

Once cucumbers start to fruit, they have to be picked every day, otherwise the value of the commodity 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 cucumbers 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 cucumbers on the market is becoming more and more problematic
