For rice leaf roller larvae of the 3rd instar and above, on the one hand they are protected because they are wrapped inside the rice leaves, and on the other hand they are insensitive to nereistoxin-type pesticides such as monosultap and to organophosphorus pesticides such as chlorpyrifos, methamidophos and monocrotophos, so the control effect after spraying is poor. Relatively speaking, older rice leaf

Can emamectin benzoate control the rice leaf roller?
Emamectin benzoate is a new type of high-efficiency semi-synthetic antibiotic insecticide synthesized starting from the fermentation product avermectin B1. It has the characteristics of biological pesticides such as ultra-high efficiency, low toxicity (the formulation is nearly non-toxic), no residue, and no pollution. Compared with avermectin, its insecticidal activity is first increased by 1-3 orders of magnitude. It has extremely high activity against the larvae of Lepidoptera insects and many other pests and mites. It has both stomach poison action and contact action, and has very good effects at very low doses (0.084~2g/ha), and in the process of controlling pests it is harmless to beneficial
