Problems solved by technology

Even if the state expressly prohibits the use of pesticides such as methamidophos, methyl parathion and other pesticides, farmers still continue to use them. Therefore, poisoning incidents caused by excessive residues of highly toxic pesticides in agricultural products have occurred frequently. Currently, there is only one way to eliminate pesticide residues Washing with water, but cannot fundamentally eliminate pesticide residues
[0003] At present, the preparations or drugs that degrade pesticide residues in the market have the defects of poor degradation effect, slow speed, and lack of broad spectrum

Abstract

The invention discloses a preparation for degrading pesticide residue in plants and a preparation method for the same. The preparation is prepared from the following raw materials: trichoderma harzianum spore powder, maltose, ferrous sulfate, magnesium sulfate, compound amino acid, boric acid, ethoxyl trisiloxane and 98 percent Tween-80. The preparation method comprises the following steps of: adding 5 to 15mg of trichoderma harzianum spore powder into 1,000ml of water, uniformly mixing, adding 0.5 to 1.0ml of 98 percent Tween-80, adding 1 to 5g of maltose, 0.03 to 0.07g of ferrous sulfate, 0.4 to 0.8g of magnesium sulfate, 0.4 to 0.7g of compound amino acid, 0.02 to 0.06g of boric acid and 5ml of ethoxyl trisiloxane, and mixing to obtain the preparation. According to the preparation for degrading the pesticide residue in the plants and the preparation method for the same, the process is simple, the operation is simple and convenient, and the prepared preparation can radically reduce the pesticide residue in the plants and improve the edible safety of melons and fruits.

Description

technical field [0001] The invention relates to a pesticide residue preparation and a preparation method, in particular to a preparation and a preparation method for degrading pesticide residues in plants. Background technique [0002] Pesticides are necessary production products in agricultural production, and play an important role in preventing and controlling pests and diseases, removing weeds, and improving the yield and quality of agricultural products. But on the other hand, with the massive and unreasonable application of pesticides, serious pollution and damage to the ecological environment have been caused, and the harm of pesticide residues in food to human health has become increasingly apparent. The abuse of pesticides in vegetables and fruits in my country is quite serious. The results of national supervision and spot checks on product quality announced by the AQSIQ in 2008 showed that the problem of excessive pesticide residues in vegetables is prominent: one...
