Abstract

The invention relates to the pesticide remains fast detecting reagent box and its using method. The reagent comprises the extracting reagent, the base material, the color-showing agent and enzyme. It judges the whether the pesticide remains surpass the standard amount through the color-comparison reaction. The manufacturing of the box is very simple, and cost is very low and the detection process is fast.

Description

1. Technical field [0001] The invention relates to a rapid detection kit for pesticide residues and its usage. It is dedicated to the rapid detection of organophosphorus and carbamate pesticide residues in agricultural products, food, water, soil, poisonous organisms, especially grain, vegetables, fruits, Chinese medicinal materials and meat. 2. Background technology [0002] With the rapid development of my country's industry and the strategic adjustment of agricultural and industrial structures, especially the transformation of cultivation methods, the occurrence and harm of harmful organisms such as pest weeds, which were originally secondary or even quarantine, are becoming more and more serious, and drug resistance continues to rise. , leading to an increase in the amount of pesticides and the frequency of application. The abuse of highly toxic and high-residue pesticides has been repeatedly prohibited. Some use pesticides not in accordance with the regulations, and som...
