Description
Technical Field
The invention relates to the technical field of pesticide detection, in particular to a device for quickly detecting pyrethroid pesticide residues in pasture of an animal farm.
Background
Forage grass, generally refers to grass or other herbaceous plants used by raised livestock. The pasture has strong regeneration capacity, can be harvested for many times in one year, and is rich in various trace elements and vitamins, so the pasture becomes the first choice for raising livestock. The pasture grass not only contains various nutrient substances necessary for livestock, but also contains crude fiber which is particularly important for maintaining the health of ruminant livestock, and the crude fiber cannot be replaced by grain and other feeds.
The control of the insect pest of the pasture is one of the key problems to be solved most by pasture planting, and because pyrethroid pesticides are commonly used in the pasture planting process, the pyrethroid pesticides are synthesized by simulating the chemical structure of natural pyrethrin, have selective toxicity, are quickly metabolized and excreted in mammals, have little environmental residue and the like. It can be used as contact insecticide to contact with the surface of insect or oral organ and then permeate into insect, or corrode wax layer of insect, or block air valve to kill the pests in pasture. However, most of the existing pesticide residue detection devices analyze and detect harmful components of human bodies or animals and products thereof, and few devices detect pyrethroid pesticides in pasture fed by herbivorous animals.
