ルフェヌロンBenzoylurea殺虫剤です。クロルフェナピアピロール殺虫剤と寛大な自殺です。Indoxacarbオキサジアジン殺虫剤です。 3つは独自の殺虫剤効果を持っています。この記事は、次の側面から3つの成分を簡単に分析および比較して、製品の選択に関するいくつかの参照を提供します。
1。殺虫剤法
ルフェヌロンには、胃の毒と接触の殺害効果、全身吸収、強い卵の殺害があります。クロルフェナピルは胃の毒と接触の殺害効果を持ち、特定の全身性効果を持ち、卵を殺しません。 Indoxacarbには胃の毒と接触の殺害効果があり、全身効果がなく、卵を殺しません。 3つはすべて、主に胃の毒と接触の殺害であり、農薬を適用する際に浸透剤またはエクステンダーを追加すると、殺害効果が大幅に改善されます。
2。殺虫剤スペクトル
Lufenapyr is mainly used to control leaf rollers, diamondback moths, cabbage worms, beet armyworms, armyworms, whiteflies, thrips, rust ticks and other pests, and is particularly effective in controlling rice leaf rollers; chlorfenapyr has excellent control effects on boring, sucking and chewing pests and mites, especially against resistant pests such as diamondback moths, beet armyworms, armyworms, leaf rollers, American leafminers, bean pod borers, thrips, and red spiders; indoxacarb is mainly used to control beet armyworms, diamondback moths, cabbage worms, armyworms, cotton bollworms, tobacco budworms, and leaf rollers. - So the comparison of insecticide spectrum is: chlorfenapyr>lufenapyr>Indoxacarb
3。昆虫の死の速度
After the insects contact the pesticide and feed on the leaves with the pesticide, their mouths are anesthetized within 2 hours, and they stop feeding, thus stopping harming the crops, and the peak of insect death is reached in 3-5 days; 1 hour after chlorfenapyr is sprayed, the insects become less active, spots appear, the color changes, the activities stop, they become comatose, and limp, and eventually die, and the peak of insect death is reached in 24 hours; within 0-4 hours after indoxacarb, the insects stop feeding and are immediately paralyzed, and the insects' coordination ability will decrease (which may cause the larvae to fall from the crops), and they usually die within 1-3 days after the application of the pesticide. So the comparison of insecticidal speed is: chlorfenapyr>indoxacarb>Lumefantrine。
4。効果の期間
Lufenuron has a strong egg-killing effect, and the insect control time is relatively long, up to 25 days; chlorfenapyr does not kill eggs, but only has outstanding control effect on old insects, and the insect control time is about 7-10 days; indoxacarb does not kill eggs, but kills all lepidopteran pests, and the control effect is about 12-15 days. So the comparison of the duration of effect is: lufenuron>indoxacarb>クロルフェナピア。
5。葉の保持率
The ultimate goal of insecticide 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 perception of the people. The leaf retention rate is the ultimate indicator to measure the value of the product. Comparing the control effect of rice leaf roller, the leaf preservation rate of lufenuron can reach more than 90%, indoxacarb reaches 80%, and chlorfenapyr reaches about 65%; so the comparison of leaf preservation rate is: lufenuron>indoxacarb>クロルフェナピア。
6。安全
So far, there has been no phytotoxicity response to lufenuron, and the agent will not cause the piercing-sucking pests to become rampant again, and it has a mild effect on the adults of beneficial insects and predatory spiders; chlorfenapyr is sensitive to cruciferous vegetables and melon crops, and is prone to phytotoxicity when used at high temperatures or high doses; indoxacarb is highly safe, with no phytotoxicity response, and vegetables or fruits can be picked and eaten the next day after application. So the comparison in terms of safety is: indoxacarb>lufenuron>クロルフェナピア。
7。薬物費用
The comparison of drug cost is: indoxacarb>chlorfenapyr>ルフェヌロン。 1つの文で実際に使用する3つの全体的な感覚を評価するために、Lufenuronは初めて使用された場合に非常に効果的だと感じますが、2回連続で使用した後は非常に効果的です。それどころか、Chlorfenapyrは初めて使用すると非常に効果的だと感じていますが、2回連続で使用した後、非常に普通に感じます。 Indoxacarbの効果は、ほぼ2つの間にあります。
