[0023] In the present invention, the preparation method of the pesticide residue degradation agent described in the above-mentioned technical scheme preferably comprises the following steps:
[0024] Dissolve potassium permanganate, potassium dihydrogen phosphate, polyferric sulfate and nano silicon dioxide in water.
[0025] In the present invention, the pesticide residue degradation agent is ready-to-use and ready-to-use.
[0026] The present invention also provides the application of the pesticide residue degradation agent in degrading crop residue pesticides. The application is preferably: spraying the pesticide residue degradation agent on the crops for 2-3 times with an interval of 5-7 days.
[0027] In the present invention, the crops preferably include tobacco, leafy vegetables and fruit trees. The tobacco is preferably harvested before the tobacco leaves.
[0028] In the present invention, the pesticides preferably include organophosphorus and organochlorine pestici...
Embodiment 1
[0034] Potassium permanganate, potassium dihydrogen phosphate, polyferric sulfate and nano silicon dioxide were weighed respectively, potassium permanganate was first dissolved in a small amount of water, then potassium dihydrogen phosphate, polyferric sulfate and nano silicon dioxide were added respectively, Make the mass concentration of potassium permanganate 0.1%, potassium dihydrogen phosphate 0.5%, polyferric sulfate 0.1% and nano-silicon dioxide 0.05%, add water to 100%, and obtain tobacco pesticide residue degradation water agent.

Abstract
The invention provides a pesticide residue degradation agent. Raw material components include potassium permanganate, monopotassium phosphate, polyferric sulfate, nano silicon dioxide and water. The invention further provides application of the pesticide residue degradation agent to degradation of crop pesticide residues. The degradation rate of the pesticide residue degradation agent to the pesticide residues ranges from 63.8% to 100%, and high degradation efficiency is achieved. The provided tobacco pesticide degradation agent has a good degradation effect on anisole, imidacloprid, acetamiprid, dinotefuran, thiamethoxam, trifloxystrobin, tebuconazole, nitenpyram and diniconazole applied to tobacco and other crops, and is obvious in degradation function especially for the nitenpyram and the imidacloprid.
Description
Technical field [0001] The invention belongs to the field of disinfectants, and specifically relates to a pesticide residue degrading agent and its preparation method and application. Background technique [0002] Pesticides commonly used in flue-cured tobacco production in my country mainly include insecticides, fungicides, nematicides, herbicides and growth regulators. Large and long-term use of chemical pesticides has caused an increase in pesticide residues in tobacco leaves, and at the same time, the resistance of pests and diseases has increased. Factors such as the enhancement and re-emergence of pesticides have seriously affected the safety of cigarette products and the sustainable development of tobacco agriculture. Therefore, it is very important to develop or select efficient pesticide degradation products, and it is also important to the sustainable development of modern tobacco agriculture and industry. significance. [0003] At present, degradants for eliminatin...
