Among the varieties of systemic conductive insecticides, there are many varieties of organic phosphorus, carbamate, organic nitrogen and nicotine. Among the organochlorine insecticides, except for the weak systemic action of lindane, other varieties have almost no systemic action; while common pyrethroid insecticides have no systemic action. Most of the systemic organophosphorus pesticides are highly toxic, and many varieties are banned because of their high toxicity or long residual time, such as phosphorus absorption. Among the five organophosphorus high-toxic varieties that were eliminated at the end of last year, three varieties of methamidophos, monocrotophos and phosphonamine were systemic insecticides. Of course, among several low-toxic insecticides that have been promoted and applied in recent years, imidacloprid and fipronil are also systemic insecticides. Common types of systemic insecticides are listed below.
one. Organic nitrogen insecticide
1, insecticidal double
1 Mechanism and characteristics
The insecticidal double is a silkworm toxin insecticide, which is a nerve poison. The insects show dullness, slow movement, loss of ability to invade crops, stop development, soften the body, lick, and die until the insects contact and take the medicine. The insecticidal double has a strong systemic action and can be absorbed and transmitted by the leaves and roots of the crop.
