Tepiride mainly acts on insect larvae to prevent the peeling process and kills pests, and has a strong ability to kill eggs and insects. It is applicable to the control of pests resistant to pyrethroids and organophosphorus pesticides.
1、Prevention objects
Dellubenzuron is highly effective against lepidopteran pests of many crops, especially against noctuid pests such as beet armyworm, spodoptera litura, cotton bollworm and other resistant pests.
2、Main features
1. Good egg killing effect and long duration (about 10 days): the liquid medicine can directly kill eggs by spraying on the leaves or eggs of crops. More than 95% of the eggs laid by pests within 48 hours after the leaves were treated with drugs could not hatch; The eggs laid within 10 days could not hatch normally; Although adults can not die after contacting with chemicals or feeding on dews containing chemicals, their egg production and hatchability are significantly reduced, which can effectively reduce the source of pests.
2. Effective pest control: after contacting with the pesticide and feeding on the medicated leaves, the pests will be anesthetized and stop feeding within 2 hours, stop harming crops, and reach the peak of dead insects within 3-5 days. The duration of validity is about 10 days.
3. Low toxicity, low residue, safe for use: In addition to low toxicity to fish and mammals, it is selective to most beneficial insects, safe for humans, animals, crops and the environment, and suitable for the pollution-free integrated management of pests.
3、Usage
1. Single dose use: Dellubenzuron has strong egg killing and insect killing effects: it can control cotton bollworm, beet armyworm and other pests, and the mortality rate of 1-day old eggs can reach 87.30% when 5% Dellubenzuron suspension is sprayed with 1000 times liquid; For cotton bollworm 2? The 5th instar larvae had higher stomach toxicity. The control effect was still more than 89% 15 days after application, which was highly safe for crops.
2. Use of compound preparation: in order to improve the control effect, it can be used to control the pests that have developed drug resistance, especially the effect.
