Abstract
" duo Chong Jing " (various insects utter annihilation) emulsion, a kind of agricultural fungicides that is mixed, be mixed by a certain percentage by the effective ingredient of agricultural chemicals such as Rogor, isoprocarb and decis and form, the control of multiple insect pest of suitable paddy rice, vegetables, fruit and other crops of holding concurrently, especially remarkable to water rice hopper, leafhopper, cabbage caterpillar, citrus red mite, cotten aphid, two-spotted spider mite control efficiency.Can overcome the pesticide resistance of Rogor, the tool obvious synergistic effect, efficient, low toxicity, wide spectrum, formulation rate is few, cost is low, and one executes use more.
Description
The present invention relates to a kind of agricultural insecticide.
Containing O, O-dimethyl-S-(N-methylamino formyl methyl) phosphordithiic acid fat is more than 40 percent, and other compositions are the agricultural insecticide of emulsifier and solvent, and trade name is a Rogor, is the special-purpose agricultural chemicals of crop pests such as vegetables control.Be characterized in and tag, stomach toxicity and certain interior suction fumigation action arranged, can prevent and treat many insects such as vegetables cabbage caterpillar, aphid, citrus red mite, cotten aphid, two-spotted spider mite, sugarcane aphid, but because of service time longer, above-mentioned insect has produced serious pesticide resistance, and insecticidal effect obviously descends, and cabbage caterpillar is become invalid, to the control efficiency of aphid also variation, the trend that is eliminated is arranged.
Solve the pesticide resistance of Rogor with 40% composite happy Cyano chrysanthemate of Rogor and decis, can be used for the control of vegetables, the various insects of fruit tree, but restricted application especially can not produce good effect to the control of rice grub.
The contained effective ingredient of isoprocarb missible oil be o-isopropyl phenyl-N-methyl mephenesin Carbamate at least 20% be used to prevent and treat rice grub-rice fulgorid, rice leafhopper, knock down fast, lethality is big, shortcoming is that insecticidal spectrum is very narrow.
The objective of the invention is to propose a kind ofly can be used for various pests control, low toxicity, can overcome anti-medicament, can enlarge the novel mixed insecticide of desinsection spectrum width again dimethoate emulsion.
The " duo Chong Jing " (various insects utter annihilation) emulsion that the present invention proposes, it is characterized in that containing O, O-dimethyl-S-(N-methylamino formyl methyl) phosphorodithioate and o-isopropyl phenyl-N-methyl carbamate, and (S)-2-cyano group-S-phenoxy benzyl-(1R, 3R)-3-(2, the 2-dibromo vinyl)-2,2-dimethyl cyclopropane carboxylic acid ester, three kinds of composition total amounts account for 30～40% of emulsion, O wherein, O-dimethyl-S-(N-methylamino formyl methyl) phosphorodithioate accounts for 20～30%, o-isopropyl phenyl-N-methyl carbamate accounts for 5～15%, (S)-and 2-cyano group-S-phenoxy benzyl-(1R, 3R)-3-(2, the 2-dibromo vinyl)-2,2-dimethyl cyclopropane carboxylic acid ester accounts for 0.0～0.2%.
Embodiment 1:30.01% " duo Chong Jing " (various insects utter annihilation) emulsion, contain O, O-dimethyl-S-(N-methylamino formyl methyl) phosphorodithioate 20%, contain o-isopropyl phenyl-N-methyl carbamate 10%, contain (S)-2-cyano group-S-phenoxy benzyl-(1R, 3R)-3-(2, the 2-dibromo vinyl)-2,2-dimethyl cyclopropane carboxylic acid ester 0.01% adds emulsifier 0204C10%, adds benzene class and alcohols mixed solvent to 100% again.
Every mu of dispensing amount of 30.01% " duo Chong Jing " (various insects utter annihilation) emulsion is 2 liang, can prevent and treat rice fulgorid more than 94.7%, is 95% to the citrus red mite preventive effect, to the control rate of vegetable aphid also more than 90%.
" duo Chong Jing " (various insects utter annihilation) emulsion has solved the pesticide resistance of crop pests to Rogor effectively, toxicity is little, the desinsection spectrum width, potion is used more, multiple insect pest for vegetables, melon and fruit and paddy rice all has remarkable prevention effect, and the unit are formulation rate is few, and the effective ingredient amount is few, cost is low, and tangible economic and social benefit is arranged.
