11 hybrid insecticidal “remedies”! Killing insects and killing eggs

Hello, come to consult our products !

Most insecticides enter the insect body through its mouthparts and play its role in killing insects.According to the feeding characteristics of pests, insects can be classified according to the characteristics of mouthparts.

                           Pest control of chewing mouthparts

When harming crops, these pests must eat leaves or other tissues of plants, causing damage such as leaf absence, etc., mainly including larva of Lepidoptera (such as leafworms, noctuidae larvae, etc.), pests of coleoptera (beetles), nymphs and adults of orthoptera (locusts, crickets, grylcrickets), and larva and adults of hymenoptera.

Strong stomach toxicity of pesticides to the most significant effect of this kind of pest control, such as the most commonly used organophosphate pesticides, part of the stomach toxicity effect of carbamate pesticides, quasi deinsectization strain pesticides, nereid toxins pesticides, benzoyl urea pesticides, part of the insect hormones insecticide, abamectin pesticide etc.

Insecticides that are good for internal use but poor at handling and stomach toxicity are generally ineffective against such pests.

                              Control of stinging and sucking pests

These pests, which suck the SAP from the young tissues of plants through their mouths, cause damage, including aphids, mealworms, leaf cicadas, bugs, bug shells, thrips, and mosquitoes.

For this kind of pests, it is advisable to choose insecticides with good internal absorption or infiltration and good gastric toxicity.The main absorbent insecticides are organophosphorus insecticides, carbamate insecticides, bombyx toxin insecticides, imidacloprid insecticides, acetamiprid insecticides and so on.

Stinging and sucking pest control agents recommended:

22.4% Spirotetramat : kill insect kill egg, the efficacy of direct pest love to eat.

15% Cyanobromine +Thiacloprid: it has gastric toxicity, contact and internal absorption, and protects crops in an all-round way.

26% Meperfluthrin+acetamiprid : the preferred agent for resistance to small insects, quick effect.

70% imidacloprid: kill insects kill eggs, the effect of direct pest love to eat the place.

Prevention and treatment of underground pests

The main underground pests are grubs (scarab larvae), ground tigers, crickets, mole crickets, ground maggots and bud maggots, leaf turtles, etc.According to the characteristics of life, these pests may live in the soil or on the surface of the soil at a certain stage, and the harmful parts are special. The combination of pesticide and soil particles should be considered when applying pesticides.

Some pesticides will lose their insecticidal effect when combined with soil. Therefore, the selection of insecticide composition is very important. Insecticide granules can be used for soil control or ground spraying, or insecticide baits can be used to kill insects.

Recommended underground pest control agents:

10%  fosthiazate : Specifically for underground pests.

Use for specific pests

In melon crops, if the control effect of bactroids is not good, bactroids’ tendency to sweet and sour food can be considered and attractants can be made to control bactroids.

For drill – eaten pests

For example, the prevention and control methods of longicorn sinensis are mainly concentrated liquid injection, and the insecticides with fumigation or internal absorption are better.It is necessary to control the hatching period of the eggs of codominus xylostella and Hymenoptera xylostella.Pesticide should be selected with good stomach toxicity, good touch (and has good infiltration) of insecticide.

The right combination can double the potency

The combination of Emamectin and Benzohydrazide could prolong the control efficacy period of noctuidae pests.

The combination of Emamectin and Flubicide could effectively control rice leaf roller and fruit tree edible insect.

The combination of Spiroworm ethyl ester and Avermectin had a good control effect on psyllid pear.

The mixture of Emamectin and Chlorfenapyr has the effect of killing insects and silly mites.

The combination of Spiroworm ethyl ester and Thiazinone is safe and efficient in the control of scale insect.

The mixture of Abamectin and Cyromazine can control the insect pests of the noctuidae.
