Preparation technique of pesticide with high permeability

Abstract

The key point of this agricultural chemical preparation technique is that besides the addition of emulsifier, a water-soluble osmosing agent must be added with quantity of 3-90% and the specification of osmosis time for the agrecultural chemical preparation is 20 sec -120 min. This invention may be used for new variety of pesticide, existing pesticide and preparation, and compound preparation. The content of effective components in the pesticide reduces by 40% as compared with that of the existing preparation technique, but the effect of insect-killing and prevention and curing is equivalent or slightly higher. It can delay the drug-resistance of harmful insects, reduce the environmental pollution, and reduce the cost of pesticide.

Description

technical field [0001] The invention belongs to the pesticide characterized by surfactant. Background technique [0002] As we all know, most of the pesticides that are insoluble in water are processed into emulsifiable concentrates, suspending agents, wettable powders and other dosage forms by adding emulsifiers, dispersants, various additives and fillers at home and abroad, so that they can be dissolved in Only water can be sprayed on the plants to exert the medicinal effect. Pesticides that are completely soluble in water add a small amount of surfactants so that they can adhere to the plants when sprayed to exert their medicinal power. At present, the preparation products of pesticide processing technology have low penetration. After field spraying, more than 95% of the pesticides cannot play a role but are lost and volatilized, causing pollution to the atmosphere, soil, water quality and even the entire ecological environment. There are two current countermeasures. On...

Problems solved by technology

At present, there are many kinds of synergists at home and abroad. There are synergists, synergists, and synerth ethers abroad; domestically, there is synergist phosphorus, but these synergists are only effective for pyrethrins or carbamate pesticides. , cannot be widely applied to other types of pesticides, that is, there is no pluripotent effect of a dose

The synergistic methods of the above two kinds of pesticides can only select the best formula through laboratory bioassay toxicity to preliminarily determine the drug effect during preparation, which makes it difficult or impossible to study the formula with the best effect in the chemical laboratory. It is extremely difficult for units without bioassay equipment and technology to develop compound and synergistic pesticide preparations
