With the continuous improvement of people's living standards, people have higher requirements for the quality of food. The problem of food safety and hygiene, especially the pollution and residue of pesticides in fruits, vegetables and food, has become a hot spot for the people, and it is pollution-free. Agricultural products, etc., have also been more and more popular with people, the following is a small series of Nanjing Dr. Bang to tell you about the classification of several common pollution-free pesticides . The in vitro culture of cells and tissues has become an indispensable part of life research and practice. A wide variety of cell types are cultured, from viruses to bacteria and fungi, from human cells to animal and plant cells. Some cells and tissues can be grown in suspension, but a considerable number of mammalian cells require surface attachment. Therefore, in addition to good transparency, non-toxicity and sterility, the culture flasks, Culture Plates and culture dishes used to provide the in vitro culture environment of cells also need to be surface-modified to enable them to adhere, divide and grow. 75 cm cell culture flask,t75 cell culture flask,suspension cell culture flask Yong Yue Medical Technology(Kunshan) Co.,Ltd , https://www.yonyuepcrtube.com
1. According to the composition and source of pollution-free pesticides (1) Microbial source pesticides: These pesticides include microorganisms and metabolites such as Beauveria bassiana, Bacillus thuringiensis, nuclear polyhedrosis virus, nematodes, microsporidia, and Antibiotics, etc.
(2) Plant-derived pesticides: These pesticides include plant bodies and their metabolites such as gibberellic acid , brassinolide , quercetin, nicotine, rotenone, pyrethrum, gene activators, and the like.
(3) Animal-derived pesticides: These pesticides include animals and their metabolites, such as Trichogramma, grass mites, insect hormones, animal oils, animal toxins, and the like.
(4) Mineral source pesticides: such as mineral oil emulsion, stone sulfur mixture, rosin mixture and so on.
(5) Biochemical pesticides: These pesticides refer to artificial mimics such as deltamethrin, avermectin, and flubenzuron.
(6) Other pollution-free pesticides: These pesticides mainly include low-to-low-toxicity and low-residue pesticides in chemical pesticides, such as chlorinated rosin copper, chlorpyrifos, amphetamine, and anti-polysaccharide.
2, according to the control objects of pollution-free pesticides (1) pollution-free pesticides: such as Bacillus thuringiensis, resveratrol, spinosad, cypermethrin, avermectin and so on.
(2) Non-polluting fungicides: such as carbendazim , Bordeaux mixture, Jinggangmycin, and ether oxystrobin.
(3) Non-polluted rodenticides: such as red sea onions, type C botulinum toxin.
(4) Non-polluting herbicides: such as herbicides, anthrax spp.
(5) Non-polluting plant growth regulators: such as gibberellic acid, brassinolide, corn auxin, and the like.
(6) Non-polluting pesticide activators: such as activated esters.
Strengthening the safe use of pesticides and improving the level of safe use of pesticides in the production process of agricultural products is to ensure that agricultural products are free of pesticide residue pollution. Therefore, when you choose pesticide products, you can refer to the above information carefully!
