In addition to chlorpyrifos, these 3 kinds of insecticides deserve attention

Lufenuron, carbofuran and indoxacarb have different insecticidal effects, and it is not possible to generalize which one is better or worse. The following aspects of the three components of a simple analysis of the control, for everyone to screen the product to provide some reference.

1. Insecticidal mode

Lufenuron has gastric poisoning and poisoning by touch,SWAN insect killer supplier no endosuction, strong egg killing; carbofuran has gastric poisoning and poisoning by touch, some endosuction, no egg killing; indoxacarb has gastric poisoning and poisoning by touch, no endosuction, no egg killing; all the three are mainly gastric poisoning and poisoning by touch, and the killing effect will be greatly improved by matching with infiltrating agent/expanding agent when applying the drug.

2.Insecticidal spectrum

Chlorfenapyr is mainly used to control leaf borer, cabbage moth, cabbage greenfly, beet nightshade, twill nightshade, whitefly, thrips, rusty wall louse and other pests, and it is especially outstanding in the control of rice leaf borer;SPRITEX insect killer manufacturer Chlorfenapyr has excellent preventive effect against drilling, piercing, sucking and chewing pests and mites, and it has remarkable effect especially on antipests of cabbage moth, beet nightshade, twill nightshade, leaf borer, American spotted fly, pod borer, thrips, red spider mite, etc.; chlorfenapyr is also effective in the control of leaf borer. Indoxacarb is mainly used for the control of beet moths, cabbage moths, cabbage greenfly, oblique moths, cotton bollworm, tobacco bollworm, leaf roller and other lepidopteran pests. So the comparison by insecticidal spectrum is:

Fenitrothion > lufenuron > indoxacarb.

3.Death speed

Lufenuron, after contacting the agent and feeding on the leaves with agent, the pests will be anesthetized within 2 hours, stop feeding, thus stop harming the crops, and the peak of dead insects will be reached in 3-5 days; carbofuran will be weakened in 1 hour after the drug is injected,Chinese RAMBO Insecticide spray and the pests will have spots, color change, stop activity, coma, paralysis, and ultimately lead to death, and the peak of dead insects will be reached in 24 hours; ninhydrin will stop feeding within 0-4 hours; ninhydrin will stop feeding within 4 hours; ninhydrin will stop feeding within 4 hours. Within 4 hours, the insect stops feeding, then paralyzed, the coordination ability of the insect will be reduced (which can lead to larvae falling from the crop), generally die within 1-3 days after the drug. So the comparison by killing speed is:

Carbaryl > Indoxacarb > Lufenuron.

4.Persistence period

Lufenuron has strong ovicidal effect, the control time is longer than general, the highest temperature can be up to 25 days; Carbofuran does not kill the eggs, only to some high-grade insects with outstanding preventive effect, the cost of control time is about 7-10 days; Indoxacarb does not kill the eggs, and it is used to kill the Lepidoptera in a unified way, and the preventive effect is about 12-15 days. So according to the holding period management comparison is:

Lufenuron > indoxacarb > carbofuran.

5. Leaf preservation rate

The ultimate goal of pest control is to prevent pests from harming crops. As to whether the pests die quickly or slowly or more or less, it is only the people's perception, and the leaf retention rate is the ultimate index to measure the value of the product. According to the control effect on rice leaf borer, the leaf retention rate of lufenuron can be more than 90%, indoxacarb can be up to 80%, and bromoxynil can be up to about 65%. Therefore, according to the comparison of leaf retention rate.

Lufenuron > Indoxacarb > Bromoxynil.

6.Safety

So far, lufenuron has no harmful effects, at the same time, this agent will not cause the stinging pests to become rampant again, and it is mild to the adult beneficial insects and feeding spiders; carbofuran is sensitive to cruciferous vegetables and melon crops, and it is easy to be used at high temperature or high dose; indoxacarb is highly safe, with no harmful effects, and the vegetables or fruits can be picked and eaten the next day after the application of the drug. So from the safety comparison is:

Indoxacarb > lufenuron > carbofuran.

Lufenuron has a general effect when used for the first time, and the effect is very unusual when used for two consecutive times; carbofuran, on the contrary, has a very good effect when used for the first time, and an ordinary effect when used for two consecutive times; the effect of indoxacarb is roughly in between the two.
