During the period when pests reproduce the fastest and cause the most serious damage, multiple pests often coexist, and generation overlap is serious. Many pesticides have unsatisfactory control effects, and a large number of fruits are damaged, resulting in huge yield losses. Today, I would like to introduce to you an excellent insecticide, which has a good control effect on the eggs and larvae of resistant pests. This agent is lufenuron.
1. Insecticide mechanism
Lufenuron is the latest generation to replace urea insecticides. The principle of insecticide is mainly by acting on insect larvae, inhibiting chitin synthesis to prevent the further growth and peeling process of insect exoskeleton, thereby killing pests. It has strong egg-killing and insecticidal capabilities. It has a unique killing effect on thrips, rust mites, whiteflies and other pests. It is particularly effective against pests such as beet armyworm, cotton bollworm, Spodoptera litura, Spodoptera frugiperda, and whitefly that have developed resistance to organophosphorus and pyrethroid pesticides.
2. Main features
(1) Broad insecticidal spectrum: Lufenuron has a good control effect on Lepidoptera pests such as cotton bollworm, beet armyworm, striped armyworm, diamondback moth, as well as Pteroptera pests such as tobacco whitefly, thrips, aphids, and other harmful mites such as rust mites, cinnabar leaf mites, and two spotted leaf mites.
(2) Kill eggs: Lufenuron not only kills insects, but also has a good killing effect on eggs. More than 95% of the eggs laid by pests within 48 hours after the leaves are treated with the pesticide cannot hatch. Eggs laid within 10 days cannot hatch normally.
(3) Long validity period: Lufenuron has a very good killing effect on eggs and larvae. After the pests feed, the mouth will be anesthetized within 2 hours and stop feeding, thus stopping harming the crops. The peak of dead insects will be reached in 3 to 5 days. The validity period is 15 to 25 days.
(4) High efficiency, low toxicity and no residue: Lufenuron is safe for most beneficial insects and safe for humans, animals, crops and the environment. It is a new pesticide with high efficiency, low toxicity and low residue, suitable for comprehensive management of pests without pollution.
3. Applicable crops
The agent can be widely used in tomatoes, peppers, peanuts, corn, soybeans, cotton, potatoes, grapes, apples, pears, walnuts, pomegranates, persimmons, kiwis, peaches, lychees, mangos, longans and other crops.
4. Prevention and control objects
Lufenuron mainly controls dozens of pests and harmful mites, such as the striped armyworm, sugar beet armyworm, flower thrips, tobacco armyworm, cabbage armyworm, eggplant fruit borer, diamondback moth, white planthopper, two spotted leaf mite, etc.
5. How to use
In order to improve the insecticidal effect, it can be mixed with emamectin benzoate, abamectin and other chemicals to achieve good quick effect and long lasting effect.
To control pests such as cotton bollworm, beet armyworm, Spodoptera litura, and diamondback moth, it can be used in the early stages of pests. Use 5% emamectin lufenuron suspension 16-30 ml/mu, mixed with 30 kg of water, and spray evenly on the stems and leaves to prevent egg mortality of 87.30%; the larval control effect reaches more than 89%.
