What is the mechanism of influence of the action of insecticides and how to carry out the selection of a suitable insecticide?

August is here and soon it will be pest season again. This year has been warmer and although hot, our fellow farmers have had some benefits in that pests are not active in the heat. However, come August 9, we will have another headache.

Since there are no specific areas scheduled to deal with pest problems, I don't have any special cases or actions to share today. However, I can share with you some tips on killing pests, as a sort of advance warning.

Generally speaking, the mode of action of pesticides can be categorized into stomach poisoning, contact, inhalation and fumigation.RAMBO insect killer supplier In addition, some insecticides have anti-baiting agents, attractants, sterilizers and insect growth regulators. Many insecticides have multiple roles at the same time, and can play one or more roles under certain conditions.

Touch kill refers to the penetration of chemical substances into the insect body wall (including epidermis, antennae, appendages, feet and wings) and lead to insect poisoning death.

Gastrotoxicity refers to the fact that the agent can enter the insect's body by studying the development of the insect's mouthparts and digestive information system, causing the death of the pest by poisoning.

Suction is the absorption of chemicals by plants through leaves, stems, roots or seeds. When an insect bites into toxic plant sap or bites into toxic tissue, it can lead to death by poisoning.

Fumigation is the ability of an agent to vaporize into a toxic gas or decompose into a toxic gas at room temperature and pressure. It enters the insect through its valve and respiratory system, causing the pest to die of poisoning.

In order to achieve good efficacy and improve crop safety, the selection of pesticide active ingredients and preparation process put forward higher requirements.

Microemulsion belongs to the water-based environmentally friendly dosage form with nanometer particle size.VITFE insect killer manufacturer It can effectively wet and spread on the surface of crop leaves, forming a glossy film and expanding the contact area with pests. The nano-sized chemicals can better enter into the pests and improve their insecticidal performance.

With this can be at the same time, due to have nanoscale pesticide particle size is very small, can be improved through a substantial increase to enhance the original system performance of the enterprise preparation, to realize the transformation from quantitative to qualitative change. This enhances our pesticide touch, penetration, gastric toxicity and endosorption conduction and other roles, so that the efficacy of the preparation to get their own maximum degree of release, the effect of killing bugs is more convenient and hassle-free.

However, simply killing bugs is not the ultimate goal.

Some pesticides kill bugs very well, but can be highly toxic or poisonous. In addition, formulations often contain large amounts of polar solvents, which pose a risk to non-target organisms (e.g., bees), the environment, and crops. Prolonged use may lead to drug damage or water contamination.Chinese SLEEP COOL Insecticide spray Therefore, a good pesticide should not only pursue efficacy in terms of persistence, resistance to rainfall and high efficiency in internal absorption and conduction, but also give better consideration to safety for crops and the environment. If the pursuit of efficacy at the expense of the healthy growth of crops and environmental sustainability, it would not be worthwhile.
