Description
Technical field
The present invention relates to pesticide field, particularly a kind of compound pesticide composition that contains butyl ether urea and Nitenpyram is mainly used in economic crops and paddy rice desinsection.
Background technology
The insect of economic crops and paddy rice of causing harm mainly is divided into two big classes, and wherein a class then is the insect of sucking mouthpart.The various pests such as paddy rice, fruit tree, vegetables and tea, aphid, plant hopper, thrips, leafhopper and the insect of sucking mouthpart is mainly caused harm.
Aphid is one of the primary pest of economic crops of causing harm, and the aphid of danger to vegetables mainly contains black peach aphid (cigarette aphid), radish aphid and melon aphid.Three kinds of aphids all are worldwide insects, and distribution is extremely wide.Mainly the cause harm young tender organs such as tender leaf, bud, bud of plant thrust plant tissue with sucking mouth parts, absorb a large amount of juice nutrients, so that cause the plant corpus malnutrition, and fertility is postponed.This worm secretion is honeydew, measures for a long time even meeting cover plant surface, influences photosynthesis.Often lead to dark mildew to take place.Even more serious is that this worm can be propagated multiple virus disease.
Plant hopper is one of important rice grub, is mainly brown plant-hopper, white-backed planthopper and small brown rice planthopper.Plant hopper inhales juice with adult and larva in rice clump base portion thorn, and the saliva of secretion makes paddy rice poisoning atrophy, and paddy rice point when serious of causing harm, sheet are withered and yellow, and lodging is worn the top and form plant hopper, is commonly called as the yellow pool ＂ of ＂, the withered shape of seemingly burning in full field when serious of causing harm, and No kernels or seeds are gathered, as in a year of scarcity.In addition, plant hopper also can be propagated rice dwarf virus disease and stripe virus disease, wheat rosette stunt and the corn disease of stunting.
Smaller green leaf hopper is one of important pests on the tea tree.Main harm tea tree young sprout thrusts the tender tip with the needle-like mouthpart and draws juice, consumes the tealeaves nutrient, punctures tender stem cortex when laying eggs again, makes to organize injuredly, and shoot growth is obstructed.Tea tree is killed, tealeaves atrophy, sclerosis, and internode shortening, blade tip, leaf margin are dried-up, and this dried-up phenomenon is even more serious during arid.Annual with the summer autumn tea maximum of being injured, the tea place summer autumn tea of causing harm serious can cause the sheet leaf is not had receipts.
Thrips mainly cause harm economic crops and paddy rice draw juice with rasping-sucking mouthparts at blade back, the silver gray spot occurs after blade is killed, and be local withered, the shrinkage distortion, and the whole-tobacco leaves roll song, blade is not opened up, similar poisoning shape.After growing point was killed, plant strain growth stopped.Adult of thrips and larva all can endanger soybean, also can propagate the viroses of plant simultaneously.
The medicine of present control sucking mouthpart insect is medicaments such as Imidacloprid, buprofezin, dimehypo, desinsection list, Buprofezin, dichlorvos, Biphenthrin, decis normally.Nowadays, various pests such as aphid, plant hopper, thrips, leafhopper produce resistance to these conventional pesticides, and preventing and treating this class pest needs a kind of efficient nonresistant agricultural chemicals.
The butyl ether urea is a kind of novel thiocarbamide Insecticidal and acaricidal agent, is widely used on cotton, fruit, vegetables and the tea tree.This medicine is a kind of selective insecticide, inhales and fumigation action in having, and changes the material of tool insecticide worm activity under ultraviolet light into, therefore should use this medicine when fine day.Can control the sensitive strain of aphid and carbamate, organic phosphor and pyrethroid are produced aphid, cicadellid and the trialeurodes vaporariorum etc. of resistance, can also control causing harm of diamond-back moth, imported cabbageworm and noctuid.This medicine can be used with most of insecticides tested and bactericide.Present domestic operating position is the control that is mainly used in diamond-back moth.50% boccaccio wetting powder of Switzerland Novartis Co.,Ltd has obtained interim registration on China's wild cabbage, registration number is LS94006.The quick-acting of butyl ether urea is fine, but the lasting effect shortcoming a bit.
Nitenpyram is a kind of novel nicotimine insecticides that Japan develops after Imidacloprid, and nineteen ninety-five is obtained registration in Japan.It is wide that this medicament has insecticidal spectrum, be widely used on agricultural and the gardening prevent eliminating aphis, leafhopper, preceding horse, Semiptera insect, consumption few (mu consumption 2～5 grams), toxicity is low, lasting medicine does not have poisoning to crop, and is safe in utilization, have synergy and acaricidal action after being mixed with organic phosphor that insect is developed immunity to drugs or carbamate chemicals for agriculture, and obtain new resistance pesticide new variety; This medicine mode of action uniqueness, insect are difficult for producing resistance, and remarkable interior suction and osmosis are arranged.
Summary of the invention
The purpose of this invention is to provide a kind of by butyl ether urea and the composite insecticide pesticide mixture preparation that forms of Nitenpyram.Synergistic effect is played in the stack that its composite effectiveness that shows and activity level have exceeded composition activity.Not only reduce a mu dosage, can eliminate sucking mouthpart class insect simultaneously to because a large amount of uses of butyl ether urea or Nitenpyram may cause the resistance that produces, its control efficiency is obviously improved, laborsaving, economical, minimizing environmental pollution is reduced farmer's burdens.
