Abstract
The invention relates to a compounded insecticide for preventing and controlling corn pests; it especially relates to a new kind-removing core from corn for preventing and controlling corn borer and aphid. The new kind-removing core from corn comprises material medicine and medication carrier. The material medicine contains 0.3-3wt% of pesticide, 0.1-2 wt.% of imidacloprid and the rest is medication carrier. By using only one times, the prevent invention of the new kind corn can prepare agricultural chemicals, and can prevent and control various corn pests at the same time such as corn borer and aphid. The abuse has been changed that aphid and corn borer need to be prevented and controlled separately. Times of preparing some agricultural chemicals and labor's intensity have been reduced. Not only it is realized easily and simply, but also work time and agricultural chemicals is saved. Work efficiency is high and effect is remarkable.
Description
One, technical field:
The present invention relates to the Recompounded pesticide of a kind of control of maize insect, particularly relate to the novel pesticide for preventing corn core losing of a kind of control of maize snout moth's larva, aphid.
Two, background technology:
Corn borer, the popular name borer belongs to the Lepidoptera Pyralidae.Corn borer is the important pests in the Maize Production, and Maize Production is constituted a serious threat, and has become the key factor that influences the corn with high yield stable yields.According to statistics, corn borer is gently taken place year, can cause the corn underproduction more than 8%, and the medium generation year underproduction 10%～15% is retransmitted and given birth to year underproduction more than 30%.Because the difficult anti-refractory of corn borer, seek the more effective method of preventing and treating is the problem that people constantly inquire into always.
Because corn borer is global agriculture major pest, very big to the Maize Production threat, each state all amount of having high input human and material resources studies and makes progress.Therefore, the method for control of maize snout moth's larva is more, no matter be cultural control, biological control, chemical control or physical control method all have some progress, and using suitably all can have certain control efficiency, wherein with the application area maximum of chemical prevention and control method.But the chemical control ubiquity lasting period is short, need repeatedly dispenser, or toxicity is big, to the unsafe weakness of people and animals.The parathion missible oil of classifying the medicament 50% of first-selected control of maize snout moth's larva with China as is example, this is as highly toxic pesticide, and often the peasant is a carrier with sand or slag, is processed into the local method granule voluntarily, not only very dangerous, and because fluid loss in process and contaminated environment.The medicine cost is higher in addition, and pest control is single, and peasant's burden is bigger.
Aphid is commonly called as aphid, aphid, except that the harm corn, also endangers crops such as Chinese sorghum, barley, vegetables.Maize aphids is clustered in the lobus cardiacus at corn seedling stage, and thorn is inhaled and caused harm.In the typhon mouth phase of corn growth, be the first Sheng phase that maize aphids takes place, this sprays medicine certain effect.Aphid is along with on plant strain growth the concentrates on newborn blade, and how intensive booting stage is causes harm in sword-like leave He on the leaf sheath, and corn juice is sucked on the limit, a large amount of close dew are drained on the limit, and the close dew that covers on the blade face influences photosynthesis, easily causes the mould parasitism, killed plant growing way is weak, depauperation, and output descends.The maize aphids peak period of causing harm is in corn booting stage, and this moment, milpa was higher, adopted relatively difficulty of spray medicine control, easily caused the dispenser personnel to poison; And control efficiency is poor, causes the corn poor pollination, and particle is not full, causes the corn underproduction even total crop failure, and dry year is bigger for the harm loss.
Imidacloprid is a chloro nicotine insecticide of new generation, has wide spectrum, efficient, low toxicity, low-residual, and insect is difficult for producing resistance, to characteristics such as people, animal, plant and natural enemies securities, and have tag, stomach toxicity and the multiple drug effect of interior suction.
Chlorophos is that a kind of toxicity is low, the organophosphorus insecticide that insecticidal spectrum is wide.Insect there is stronger stomach poison function, has action of contace poison concurrently, plant is had permeability, but inhale conduction in not having.
Parathion (parathion) is O, and O-diethyl-O-(p-nitrophenyl) thiophosphate claims 1605 again, is a kind of broad spectrum pesticide and miticide.
Acephatemet is a kind of efficient, the high malicious organic phosphor desinsection miticide of China's current production rate maximum, insect had tag, stomach toxicity, interior suction and certain fumigation action, the mite class also had ovicidal action, lasting period is longer, can keep about 10 days aphid, mite, to about 15 days of plant hopper, leafhopper, high instar larvae there is the better prevention effect.Insecticidal spectrum is wide, mainly be with missible oil to water spray, be used to prevent and treat the various pests of paddy rice, cotton, sugarcane, soybean and ornamental plants, with seed dressing, spread poison bait or spread method such as pesticide-clay mixture and be used to prevent and treat soil insect.
Three, summary of the invention:
The drawback of big, the vermins-proof effect difference of the amount of labour was invented a kind of new and effective pesticide for preventing corn core losing when the object of the invention was to overcome existing corn pesticide control pest.
Technical scheme of the present invention:
A kind of novel pesticide for preventing corn core losing contains former medicine and pharmaceutical carrier, represents with percentage by weight, and former medicine is 0.3～3% insecticide and 0.1～2% Imidacloprid mixture, and surplus is a pharmaceutical carrier.
Described insecticide is a parathion, or is phoxim, or is chlorophos, or is gram hundred pellets, or is acephatemet.
Described pharmaceutical carrier is that the sand, water, pigment of granularity 0.1～4mm is in the composite mixture of 100: 2～10: 0～2 ratio.
Positive beneficial effect of the present invention:
(1) novel pesticide for preventing corn core losing of the present invention can a dispenser, can prevent simultaneously eliminating aphis and multiple corn insect such as corn borer, and having changed aphid and corn borer in the past needs the drawback that prevent and treat respectively, has reduced spraying times and labour intensity.
(2) novel pesticide for preventing corn core losing of the present invention, not only simple and easy to do, saving of labor economizes medicine, work efficiency height, effective.Facts have proved that use this medicine, the control rate of aphid reaches more than 99%, the corn borer control rate reaches more than 80%; And can double corn stalk borer, two spotted spider mite, the first-class various pests of cockchafer controlled.Compare with spraying medicine, product of the present invention helps protecting natural enemy of aphid such as ladybug, Chrysopa, syrphus fly, has alleviated environmental pollution greatly.
(3) novel pesticide for preventing corn core losing of the present invention is safe in utilization; natural enemy, livestock and people there is not injury effect; preserve the ecological environment; two former medicines are composite have complementary widely; can improve the double effect of controlling, the expanding prevention object prolongs the longevity of residure and pesticide resistance; reduce production costs, the corn per mu yield can obviously increase.
