Problems solved by technology

As a kind of insect growth regulator, impatabo exerts gastric poisoning effect on pests, and has a long duration of effect, but the speed of killing insects is relatively slow. Since it cannot control the damage quickly, it is effective against borer pests such as Chiloborea, Chiloborea, etc. Control effect is low
On the other hand, organophosphorus insecticides such as chlorpyrifos, diazinon, fenitrothion, and trichlorfon are fast-acting insecticides with neurotoxicity, which are more effective against rice stem borer and rice stem borer, and are widely used to control rice stem borer. , stem borer damage; but these organophosphorus insecticides have a short persistence period, and their insecticidal activity against larvae above the 2nd instar is low, so the effect of controlling pests of mixed ages in the field alone is not ideal , in the case of large occurrences, it is necessary to repeatedly apply pesticides to prevent and control

[0021] Embodiment 1: Synergistic insecticidal effect of impatabo and chlorpyrifos compound on pests

[0022] The results of the synergistic assay showed that the compound formulations of impatabo and chlorpyrifos according to the active ingredients in five ratios of 1:500, 1:100, 1:40, 1:10 and 1:5 were effective against rice leaf roller, The co-toxicity coefficients of the rice stem borer and the rice stem borer ranged from 155 to 268 (Table 1), which indicated that the combination of the two single agents had a significant synergistic killing effect on the above three pests.

Abstract

The present invention discloses a high-effective low-toxic composite pesticide containing chlorfluazuron. Its composition includes basic active component chlorfluazuron 0.1-5%, one of chlorpyrifos 4-50%, fenitrothion 4-50%, diazinon 4-40%, acephate 10-60% and trichlorfon 20-60%, adjuvant 5-15% and the rest is solvent. Said invention can obviously raise effect for controlling rice leaf roller, and can be used for high-effectively controlling pale-headed striped borer and paddy borer, and can be substituted for high-toxic pesticide.

Description

1. Technical field [0001] The invention belongs to the technical field of pest chemical control, and in particular relates to a high-efficiency compound insecticide containing Chlorfluazuron for preventing and controlling various pests such as rice leaf roller, rice stem borer, and rice stem borer. 2. Technical background [0002] The rice leaf roller Cnaphalocrocis medinalis Guenee is a migratory rice pest. It is one of the main pests of rice due to its suddenness and wide range of damage. It causes white leaves. For a long time, the control of rice leaf roller has mainly relied on methamidophos, monosultap and other insecticides, among which methamidophos has a more prominent control effect, but because methamidophos is a highly toxic pesticide, it has been widely used in most of my country The province has banned its use; although insecticidal mono(double) is a bionic low-toxicity insecticide, its control effect on rice leaf rollers above 2 instars is poor, and due to long...
