What does systemic insecticide mean? Read this article to understand
Plant hormones, also called plant growth regulators, are neither pesticides nor fertilizers. Their main function is to coordinate the vegetative growth and reproductive growth of plants. For vegetables, this means regulating them reasonably according to people's requirements for vegetable yield, maturity period and quality, producing high-yield, high-quality vegetables and improving their...
The pesticide solution can reach all parts of the plant as it circulates with the water inside the plant. To understand it another way, let us explain with examples:1. Among insecticides, aphids suck the sap of crop leaves and branches, so the pesticide solution needs to be conducted through the plant's sap. Therefore, aphicides are basically all systemic. Pyrethroid pesticides are not systemic. However, abamectin only has penetrative properties and is not systemic.
2. In the concept of fungicides, there are three categories: protective, curative and eradicant, among which the latter two basically belong to systemic fungicides.
3. Among herbicides, glyphosate is a systemic pesticide, so after application on the leaves, weeds die within 5-7 days. The pesticide solution is conducted through the water inside the plant, and the weed roots are also killed. This is what is meant by pulling up the grass by the roots. Systemic insecticides are convenient to use, spraying does not necessarily need to be very thorough, and they can also be used by treating seeds, saving time and pesticide. Systemic insecticides can also be used to control pests that hide in shaded places and cause damage, such as aphids and red spider mites on the undersides of leaves. Systemic insecticides are suitable for controlling pests that pierce and suck plant sap, such as aphids, which suck the pesticide into their bodies while piercing and sucking crops. From this perspective, the mode of action of systemic insecticides also belongs to stomach-poison action.
