Pesticides

Most of the insecticides currently used are synthetic
organic
compounds
, such as organophosphates (e.g. enemy fear), chrysanthemums (e.g. chrysanthemums), organic nitrogen (e.g. insecticidal doubles) and specific insecticides (e.g. Yoleta). Enemy insects are white crystals, soluble in water, chloroform, benzene, ether, slightly soluble in kerosene, gasoline. Enemy fear, also known
DDVP, is a colorless, aromatic liquid that dissolves with most organic solvents. Lego is a white solid that is slightly soluble in water. It is soluble in most organic solvents and is often processed into emulsions. Methamidophos is also known as polyphosphate. It is a white crystal, soluble in water, ethanol and so on. Insecticides are natural chemicals -- artificial imitations of chrysanthemums. Deworming ester is an active ingredient in white chrysanthemums that has insecticidal effects. This ester is a colorless, viscous, high-boiling liquid dissolved in organic solvents such as oil. It breaks down and fails in daylight, air, high temperatures, and alkaline substances. It is an active ingredient in mosquito incense. Used in agriculture with a solution or emulsion. Synthetic insecticides for de-chrysanthemum were developed with the de-chrysanthemum ester as a model. Common varieties are cyanide chrysanthemum, bromocyanide and so on.


Organic nitrogen insecticides are a class of pesticides centered on nitrogen as an important active group. Here are three commonly used varieties. Fast-killing is a white crystal, dissolved in a variety of organic solvents, slightly soluble in water. Insecticidalalso known as ker death and . It is a colorless transparent crystal that is soluble in water and ethanol. Killing Dan is also known as Badan. It is a white crystal, soluble in water, slightly soluble in methanol, ethanol.
