Technical field
The present invention relates to agricultural technology field, specially a kind of degradation agent for reducing pesticide residue.
Background technique
Lack the basic knowledge of proper use of pesticide, most peasant households are only prevented and treated with pesticide, and reason is very simple, are killed
Worm effect is good, quick, and there are also part, peasant household is careless about practical technique, once thinking that control efficiency is bad, just increases dosage,
As a result so that pest and disease damage is produced drug resistance, when the pest and disease damage for having drug resistance and in the vegetables for endangering field, just apply bigger
Dose prevent and treat, the pesticide residue of such vicious circle, vegetables will greatly increase, and persistent pesticide is in plant, soil
With there are two types of the remaining forms in water body, a kind of to be to maintain original chemical structure, another kind is with its chemical conversion products or life
The form remaining of object catabolite.
With the development of science and technology, the exceeded pollution problem of Practice for Pesticide Residue in Agricultural Products has been on the rise, to the health of people
Very big threat is generated, as the data of investigation are analyzed, the every annual consumption of pyrethroid pesticide is up to 200 tonnes, wherein with height
Imitate cypermethrin, fenvalerate, cypermethrin, based on the pesticide dosages such as gamma cyhalothrin, thus current people by
During agricultural product produce and postpartum uses pesticides antidote, the various fungal pathogens of the killing of non-selectivity and all kinds of organic agricultures of decomposition
Medicine, it is possible to reduce Pesticide use, degrading pesticide residues improve agricultural product quality, however existing degradation agent can only reduce vegetables
