5. Comparison of leaf preservation rates
The ultimate goal of pest control is to prevent pests from harming crops. As for whether the pests die quickly or slowly, or more or less, it is just a matter of people’s perception. The leaf preservation rate is the ultimate indicator of the value of the product.
To compare the control effects of rice leaf rollers, the leaf preservation rate of lufenuron can reach more than 90%, Emamectin Benzoate can reach 80.7%, indoxacarb can reach 80%, Chlorfenapyr can reach about 65%.
Leaf preservation rate: lufenuron > Emamectin Benzoate > Indoxacarb > Chlorfenapyr
6. Security comparison
Lufenuron: So far, there are no harmful effects. At the same time, this agent will not cause the re-infestation of sucking pests and has a mild effect on adults of beneficial insects and predatory spiders.
Chlorfenapyr: Sensitive to cruciferous vegetables and melon crops, it is prone to phytotoxicity when used at high temperatures or in high doses;
Indoxacarb: It is highly safe and has no harmful effects. Vegetables or fruits can be picked and eaten the day after the pesticide is applied.
Emamectin Benzoate : It is highly safe for all crops in protected areas or at 10 times the recommended dosage. It is an environmentally friendly low-toxicity pesticide.
Safety: Emamectin Benzoate ≥ indoxacarb > lufenuron > Chlorfenapyr
7. Medication cost comparison
Calculated based on the quotations and dosages of various manufacturers in recent years.
The comparison of medication costs is: indoxacarb> Chlorfenapyr> lufenuron> Emamectin Benzoate
The overall feeling of the five potions in actual use:
The first time I used lufenuron, I felt that the effect was very average. After using it twice in a row, I felt that the effect was very extraordinary.
On the other hand, I felt that the effect of fenfonitrile was very good after the first use, but after two consecutive uses, the effect was average.
The effects of Emamectin Benzoate and indoxacarb are roughly in between.
Regarding the current pest resistance situation, it is recommended to adopt a “prevention first, comprehensive prevention and control” approach, and take measures (physical, chemical, biological, etc.) in the early stages of occurrence for effective prevention and control, thereby reducing the number and dosage of pesticides in the later period and delaying pesticide resistance. .
When using pesticides for prevention and control, it is recommended to combine plant-derived or biological-derived pesticides such as pyrethrins, pyrethrins, matrines, etc., and mix and rotate them with chemical agents to achieve the purpose of slowing down drug resistance; When using chemicals, it is recommended to use compound preparations and use them alternately to achieve good control effects.
