Lufenuronasyra benzoilurea insekticidas;Chlorfenapyrasyra pirolio insekticidas ir akaricidas;indoksakarbyra oksadiazino insekticidas. Trys turi savo insekticidinį poveikį. Šis straipsnis trumpai analizuoja ir palygina tris šių aspektų ingredientus, kad būtų pateiktos kai kurios produkto pasirinkimo nuorodos.
1. Insekticidų metodas
Lufenuronas turi nuodą skrandį ir kontaktinį žudymo poveikį, jokio sisteminio absorbcijos ir stiprios kiaušinių žudymo; Chlorfenapyras turi nuodą skrandį ir kontaktinį žudymo poveikį, turi tam tikrą sisteminį poveikį ir neužmuša kiaušinių; Indoksakarbas turi nuodingą skrandį ir kontaktinį žudymo poveikį, neturi jokio sisteminio poveikio ir neužmuša kiaušinių; Visi trys daugiausia yra nuodai skrandžio ir kontaktinis žudymas, o pridedant skvarbius ar prailgintuvus, kai taikant pesticidą, žudymo efektas žymiai pagerins.
2. Insekticidų spektras
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>indoksakarb
3. Vabzdžių mirties greitis
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>Lumefantrinas.
4. Poveikio trukmė
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>Chlorfenapyras.
5. Lapų išlaikymo greitis
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>Chlorfenapyras.
6. Saugumas
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>Chlorfenapyras.
7. Narkotikų kaina
The comparison of drug cost is: indoxacarb>chlorfenapyr>Lufenuronas. Norint įvertinti bendrą trijų jausmą, naudojant vieną sakinį: Lufenuronas jaučiasi labai efektyvus, kai naudojamas pirmą kartą, tačiau jaučiasi labai efektyvus po to, kai du kartus iš eilės naudoja jį; Chlorfenapyras, atvirkščiai, jaučiasi labai efektyvus, kai naudojamas pirmą kartą, tačiau jaučiasi labai įprastas po to, kai du kartus iš eilės jį naudoja; Indoksakarbo poveikis yra maždaug tarp dviejų.
