Organophosphorus pesticides are organic compounds containing organophosphorus pesticides for controlling plant diseases, insects and diseases. This kind of pesticide has many varieties, high efficacy, wide application, easy decomposition, and generally does not accumulate in humans and animals, and is a very important class of compounds in pesticides. So, what are the organophosphorus pesticides commonly used by farmers in the farmland management process?
“ Which are commonly used organophosphorus pesticides ?†The China Pesticide Network Xiaobian explains this issue as follows:
Commonly used organophosphorus pesticides Most of the organophosphorus pesticides produced in China are pesticides , such as parathion, endogenous phosphorus, malathion, dimethoate, trichlorfon, dichlorvos, etc. , gram powder can be used as a fungicide. In recent years, some rodenticides, nematicides, herbicides, defoliants, infertility agents, growth regulators, etc. have been synthesized. The most common organophosphorus pesticides are: trichlorfon , dichlorvos, omethoate, horse Desulforate, phoxim, chlorpyrifos and so on.
Organophosphorus pesticides are mostly toxic organophosphorus pesticides that are easily decomposed in alkaline solution and lose their virulence; only trichlorfon is easily soluble in water and becomes a more virulent dichlorvos when contacted with an alkaline solution. Endogenous phosphorus (1059), parathion (1605), phorate (3911), malathion (4049), dimethoate, etc., after oxidation, the virulence increased. Dibromophosphorus quickly loses bromine in the presence of reducing substances such as metals and sulfur-containing hydrides, forming a more virulent dichlorvos.
Finally, the Chinese pesticide network Xiaobian warm reminder: the main reasons for the high incidence of pesticide poisoning are: poor production process, poor storage, improper preparation, arbitrary abuse, poor operation, poor protection, so we must do a good job in pesticide poisoning.
Hook Strip Flat Screens
Hook strip flat screens the series applied most widely at present, Main feature as follows:
1.These products screen panel are constructed with two or three 304 or 316 stainless steel wire cloth layers with a steel backing plate combined together. Because of different mesh size, and steel backing plate, on the condition of using intensity, to get the best and most effective filtering area.
2.The above of thin wire cloth with middle and the bottom of the thick wire cloth, combined with different thickness steel backing plate together, infinitely enhance the whole screen use intensity. Because of different model and clients requirement, can choose different steel backing plate form, for example hexagonal, rectangular, square and so on, supporting the above different screen cloth, the whole cloth is divided into independent small surfaces, prevent the part excessive expansion damaged, better extend the use lifetime.
