Lufenuron exerts its insecticidal effect by inhibiting the formation of larval chitin synthase and interfering with chitin deposition in the epidermis, which prevents insects from completing normal molting and metamorphosis and eventually leads to their death. As the leading product among benzoylurea insecticides, lufenuron has maintained strong market momentum with steadily rising sales since its launch, thanks to its outstanding advantages including powerful ovicidal activity, long-lasting pest control efficacy and no cross-resistance.
With both stomach and contact toxicity, lufenuron is effective against lepidopteran larvae, piercing-sucking pests, thrips, rust mites and other pests. It is widely applicable to various crops such as fruit trees, vegetables, cotton, corn and potatoes. In addition, it causes mild impacts on beneficial insect adults and predatory spiders, fully complying with the concept of green pest prevention and control.
Nevertheless, lufenuron features relatively slow quick-acting effect, with the peak insecticidal effect appearing 3-5 days after application. It is recommended to mix or compound it with fast-acting pesticides.
1. Lufenuron + Abamectin
The compound pesticide of lufenuron and abamectin combines the molting inhibition mechanism of lufenuron and the potent stomach poisoning effect of abamectin, achieving comprehensive control over pest eggs, young larvae and old larvae. Since abamectin is prone to photolysis, pesticide application is advised in early morning or evening. Significant synergistic effects can be achieved at a mixing ratio of 1:2 or within the weight percentage range of 0.1~30 : 0.2~15.
2. Lufenuron + Emamectin Benzoate
Emamectin benzoate delivers fast-acting efficacy, while lufenuron boasts strong ovicidal performance and long-lasting effect. Their mixture can be applied during the peak egg hatching stage to the young larval stage, presenting remarkable control effects on beet armyworm, rice striped stem borer and rice yellow stem borer, and also works well against spider mites. The recommended application formula is 800-fold dilution of 5% lufenuron suspension concentrate mixed with 1000-fold dilution of 3% emamectin benzoate.
3. Lufenuron + Chlorfenapyr
Chlorfenapyr is a phenylpyrazole insecticide. The combination of pesticides with completely different action mechanisms achieves excellent control efficacy against corn armyworm, two-spotted armyworm and fall armyworm. The recommended dosage for corn seedling stage is 300-450 grams per hectare. Moreover, the mixture of abamectin and chlorfenapyr also has satisfactory control effects on rice leaf roller.
