Chlorantraniliprole is highly resistant and which pesticides can be substituted?
Due to the serious resistance of chlorantraniliprole products, the northern insecticide market in 2018 has revived, and various products that have been silent for more than ten years have come to the forefront. Among them, the highest heat is the three components of indoxacarb, guanidine, and chlorpyrifos. Niobium is a benzoylurea insecticide developed and produced by Syngenta. Insectonitrile is a pyrrole insecticide and acaricide developed by the American cyanamide company and produced by BASF in Germany. Indoxacarb is a oxadiazine insecticide developed and produced by DuPont of the United States. The insecticidal effects of the three have their own advantages, and they are superior and inferior. They cannot be generalized. The following aspects provide a simple analysis of the three components, providing some reference for screening products. Insecticide mode Urea urea has stomach poisoning and contact killing effect, no systemic absorption, strong egg killing; Insectonitrile has stomach poisoning and contact killing effect, has certain systemic action, and does not kill eggs; Indoxacarb has stomach poisoning and contact killing effect, no systemic action, no egg killing; all of them are mainly stomach poisoning and contact killing. When applied, penetrant/expanding agent will greatly improve the killing effect. Insecticidal spectrum The guanidine urea is mainly used for controlling pests such as leafhopper, diamondback moth, cabbage caterpillar, beet armyworm, Spodoptera litura, and whitefly, thrips, rust tick, etc., especially in the control of rice leaf roller; Insectonitrile has excellent control effects on drill collars, sucking and chewing pests and mites, especially among the resistant pests, Plutella xylostella, Spodoptera exigua, Spodoptera litura, C. sylvestris, Liriomyza sativae, and pods.螟, 蓟 horse, spider mites and other effects are significant; Indoxacarb is mainly used to control lepidopteran pests such as beet armyworm, diamondback moth, cabbage caterpillar, Spodoptera litura, cotton bollworm, tobacco budworm, and leaf roller moth. So the comparison of insecticidal spectrum is: Insectonitrile > carbamide > indoxacarb. Dead insect speed 虱螨Urea, after the pests contacted the medicinal agent and took the leaves with the medicinal agent, the mouth was anesthetized within 2 hours, and the feeding was stopped, thereby stopping the damage to the crop, and reaching the peak of the dead worm in 3 to 5 days; 1 hour after the fight with chlorfenapyr, the pest activity weakened, spots appeared, the color changed, the activity stopped, coma, soft, and eventually led to death, reaching the peak of dead insects in 24 hours; Insects stop feeding after 0-4 hours, and then paralyzed, the insect's ability to coordinate will decrease (which can cause the larva to fall from the crop), and usually die within 1-3 days after the drug. So according to the speed of insecticide comparison is: Insectonitrile > indoxacarb > guanidine urea. Effective period The guanidine urea has a strong egg-killing effect, and the insect control time is relatively long, up to 25 days; Insectonitrile does not kill eggs, only for the prevention of advanced insects, the time of controlling insects is about 7-10 days; Indoxacarb does not kill eggs, kills lepidopteran pests in size, and the control effect is about 12-15 days. So the comparison of the retention period is: Niobium urea > Indoxacarb > Worm nitrile. Leaf retention rate The ultimate goal of insecticide is to prevent pests from harming crops. As for whether the pests die faster or slower, they are only the sensory problem of the people. The level of leaf retention is the ultimate indicator of product value. To compare the control effects of rice leaf roller, The retention rate of guanidine urea can reach more than 90%. Indoxacarb reaches 80%, Insectonitrile is about 65%; so the ratio of leaf retention is: Niobium urea > Indoxacarb > Worm nitrile. safety There is no phytotoxicity reaction of guanidine urea so far, and the medicinal agent does not cause the sucking pests to re-suck, and it has a mild effect on the adult worms and the feeding spiders; Insectonitrile is sensitive to cruciferous vegetables and melon crops, and is susceptible to phytotoxicity when used at high temperatures or high doses; Indoxacarb is highly safe, and there is no phytotoxicity. The vegetables or fruits can be picked and eaten the next day. So the comparison from security is: Indoxacarb > guanidine > chlorfenapyr. Medication cost According to the quotation of each manufacturer in 2018 and the dose used, the comparison of medication costs is: Indoxacarb > worm nitrile > guanidine urea. In one sentence, the overall feeling of the three in actual use is evaluated: the first time the guanidine urea is used, the sensation effect is general, and the sensation effect is very unusual after two times of continuous use; the worm carbonitrile is reversed, and the first use feeling effect is very good, after two consecutive uses The effect is normal; the effect of the worm is roughly between the two.
