Because systemic insecticides have systemic conduction in the plant body, this type of insecticide has different characteristics from other insecticides. Specifically, there are the following points:

(1) More widely used

Systemic insecticides can be used in various ways, including seed treatment, soil treatment, and foliar spraying. Foliar spraying does not require too strict uniformity like contact insecticides. In general, as long as the spray is in place, good results can be received.

(2) Strong selectivity

Most systemic insecticides have strong selectivity and are generally particularly effective against piercing and sucking mouthparts pests. After being sprayed on the surface of the plant, it can be quickly absorbed into the body by the plant; when used for seed treatment, root irrigation, stem coating, and soil treatment, the conductivity is large, the efficacy is long-lasting, and it is very beneficial to protect natural enemies and beneficial insects.

(3) Can effectively kill hidden pests

Certain pests can penetrate into the leaf epidermis, roll leaves, bore holes, etc. The insecticidal effect of systemic insecticides is not affected by these hiding methods and can effectively kill hidden pests.

(4) Not affected by precipitation

If it encounters heavy rain shortly after application, contact insecticides are easily washed away by rainwater, which wastes the medicine and pollutes the environment; while systemic insecticides easily penetrate into plants and are hardly affected by rain washing.

(5) Saving labor and medicine

Many systemic insecticides have a long residual effect, and one application can maintain the insecticidal effect for one month, saving labor and medicine.

However, most systemic pesticides are very toxic to humans and animals and have residual toxicity, so special attention should be paid when using them. If the object to be treated is edible plants, the safety interval after application and the pesticide residue of the harvested product must be considered. Can not be mixed with live bacteria.

Among the systemic conductive insecticides, there are many types belonging to organophosphorus, carbamate, organic nitrogen and nicotine. Among the organochlorine pesticides, except for lindane, which has a weak systemic effect, other varieties have almost no systemic effect; while the common pyrethroid insecticides have no systemic effect. Most varieties of systemic organophosphate insecticides are highly toxic, and many varieties have been banned because they are too toxic or have a long residual time, such as systemic phosphorus. Among the five highly toxic organophosphorus species that were eliminated at the end of last year, methamidophos, monocrotophos, and phosphoramine were systemic pesticides. Of course, among several low-toxic insecticides that have been promoted in recent years, imidacloprid and fipronil are also systemic insecticides. The common types of systemic pesticides are listed below.

1. Organic nitrogen pesticides

(1) Bisultap

Mechanism and characteristics

Bisultap belongs to the worm toxin insecticide, which is a kind of nerve poison. After the insect contacts and eats the agent, it shows sluggishness, slow movement, loss of the ability to invade crops, stops development, softens the insect body, paralyzes, and until death. Bisultap has a strong systemic effect and can be absorbed and conducted by crop leaves and roots.

Control object

Rice stem borer, leaf roller, rice budworm, thrips, leafhopper, planthopper, vegetable cabbage caterpillar, diamondback moth, cabbage borer; corn armyworm, apple aphid, pear star caterpillar, citrus leaf miner, Dharma Papilio and so on.

(2) Monosultap 

Mechanism and characteristics

Mechanism is a similar species of bisultap, bisultap is a double sodium salt, and monosultap  is a monosodium salt. Mechanism is also an analogue of artificially synthesized Negrotoxin, which enters insects and is quickly converted into Necrotoxin or Dihydroxworm toxin. The drug is a competitive inhibitor of acetylcholine, with strong contact, stomach toxicity and systemic conduction effects. It has a good control effect on the larvae of lepidopteran pests. The drug is mainly used to control sugarcane, rice and other crops. Pests.

Control object

The rice stem borer, the rice stem borer, the leaf roller, the cabbage caterpillar, the sugarcane borer, the corn borer, etc.

(3) Profurite-aminium ａnd Monosultap ammonium

Mechanism and characteristics

It is an organic nitrogen biomimetic sandworm poisonous insecticide, Profurite-aminium is a diammonium salt, and Monosultap ammonium is a monoammonium salt. Profurite-aminium is similar to Bisultap, the former is ammonium salt and the latter is sodium salt. It has stomach poisoning, contact killing and systemic conduction effects on pests. The main mechanism of action is that the medicament enters the insect body and transforms into sandworm toxin, blocking the synaptic conduction of the central nervous system, causing the insect to paralyze, paralyze, and resist feeding. It is effective in preventing and controlling rice pests, has a long duration, and is safe to rice.

Control object

Chilo suppressalis, Chilo suppressalis, rice leaf roller, borer, cabbage caterpillar, cotton aphid, diamondback moth larvae, red spider, larvae.

(4) Cartap hydrochloride

Mechanism and characteristics

A broad-spectrum derivative of sandworm toxin that can be used to control Lepidoptera, Coleoptera, Hemiptera, Diptera and other pests and nematodes. It has little effect on predatory mites. Its toxicological mechanism is to block the impulse transmission of nerve cell contacts in the central nervous system and paralyze insects.

Control object

Cartap hydrochloride can be used to control many kinds of pests and nematodes such as Lepidoptera, Coleoptera, Hemiptera, Diptera, etc., and has little effect on predatory mites.

(5) Thiocyclam

Mechanism and characteristics

It is an insecticide of the silkworm toxin type, which has contact killing and stomach poisoning effects, and also has certain systemic and fumigation effects, and can kill eggs. The toxic effect on pests is relatively slow, and those with mild poisoning can sometimes resurrect. It disappears quickly in the plant body, the residual effect period is short, and the residual amount in the crop at harvest is small. The thiocyclam has a good effect on Lepidoptera, Coleoptera, and Homoptera pests. It can be used to control a variety of pests on rice, corn, sugar beet, fruit trees, and vegetables, but it is highly toxic to silkworms.

Control object

It has a good control effect on Lepidoptera and Coleoptera pests. ① Mainly control rice stem borers (steel borer, Chilo suppressalis, Chilo suppressalis), rice budworm, leaf roller, rice planthopper, rice leafhopper. ② Tea leafhoppers, tea loopers. ③ Fruit tree pests: such as green peach aphid, apple aphid, apple red spider, pear star caterpillar.

(6) Bensultap

Mechanism and characteristics

It is a silkworm-killing toxin insecticide. It is a kind of nerve poison. It has contact killing and stomach poisoning. It also has a certain systemic and fumigation effect. After insects contact and eat the pesticide, they show slowness and slow action, and lose the ability to invade crops. , Stop development, soften the body, paralyze, until death.

Control object

It is mainly used to control lepidopteran and coleopteran pests such as rice borer, diamondback moth, potato beetle, grape ear moth and so on..
