Description
One, technical field:
The present invention relates to the Recompounded pesticide of a kind of control of maize insect, particularly relate to a kind of core-dropping agent that can make corn dwarfing, control of maize various pests.
Two, background technology:
Corn borer, the popular name borer is one of important pests in the corn growth, and corn growth is threatened seriously, has become the key factor that affects the corn stable and high yields.According to investigations, the time gently occurs in corn borer, can cause the corn underproduction more than 8%, retransmits living time even the underproduction more than 30%.The method of control of maize snout moth's larva is a lot, and chemical control is more commonly used, but the chemical control ubiquity lasting period is short, needs repeatedly dispenser, and toxicity is large, to the uneasy congruent shortcoming of people and animals.Classify the parathion missible oil of medicament-50% of first-selected control of maize snout moth's larva as take China as example, this medicine severe toxicity, the peasant is carrier with sand or slag often, local method is processed into granule voluntarily.This medicine is not only dangerous, contaminated environment, and also pest control is single, and the medicine cost is higher.
Aphid is commonly called as aphid, except the harm corn, also endangers the crops such as Chinese sorghum, wheat, vegetables, is one of important crops insect of corn, and the boarding scope is wide, and reproductive order of generation is many, is the main disseminator of corn disease virus disease.The maize aphids initial phase is when corn sky fringe has just been lifted one's head, but 4～5 days amount reproductions.Along with plant strain growth, aphid is gathered on newborn blade or day fringe.Bloom the pollination stage at corn, aphid can make the corn male flower ruin, poor pollination, and the seed agensis, aphid sucks corn juice simultaneously, and the honeydew of drainage covers on the blade, affects photosynthesis, causes that easily mould is parasitic, makes corn early ageing even withered.This moment, milpa was higher, and maize male ears is wrapped up by aphid, and 2～3 leaves in top also are covered with aphid, far see corn leaf black a slice.If adopt relatively difficulty of spray medicine control this moment, the personnel that easily cause poison, and will cause the corn poor pollination as not preventing and treating, and form infertile fruit ear, can cause the underproduction over half.
Ethrel is a kind of efficient plant growth regulator in the agricultural chemicals, easily by plant absorbing, discharges gradually ethene in plant corpus, increases the peroxidase activity of plant, thereby reduces apical dominance, plant is downgraded healthy and strong, prevents lodging.In the last few years, in fertile culture of maize, along with the increase of fertilizing amount, the increase of planting density, the middle and later periods lodges, and has become the critical limitation factor of corn with high yield.The bright fat of amine has another name called DA～6, is a kind of new plant growth regulator, by the plant cell ultra microstructure, nucleic acid, protein, vitamin, the sugar part equal size in the object made in adjusting, effective growing of regulating plant, thus make all corresponding raisings of crop yield and quality.
Paclobutrazol is a kind of triazole type plant growth regulator, has the plant growth of delaying, and suppresses the cane elongation, shortens internode, promotes plant tillering, increases the plant stress-resistance performance, improves the output texts.
The agricultural chemicals chlopyrifos has another name called Lu's pyrazothion, Le Siben, is organophosphorus insecticide, have tag, stomach toxicity and fumigation action.Imidacloprid is chloro nicotine insecticide of new generation, has the characteristics such as 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 systemic action.Aphox belongs to the moderate toxicity insecticide, has to tag, fumigate and the blade face osmosis, and be the strong aphicide of selectivity, can effectively prevent and treat all aphids except cotten aphid, the aphid that organic phosphor is produced resistance is also effective.
Corn is a kind of long-stalked crop, and is many at summer rainwater, and wind is large, and plant easily lodges.Traditional sprinkling dispenser method is very inconvenient, and summer weather is warm again, and labour intensity is large, is difficult to effectively management.Control of maize snout moth's larva how, the insects such as aphid make corn with high yield, and seek more effective medicine is the continuous problems to discuss of people always.
Application number is that 200710047658.8 patent application relates to a kind of chlopyrifos Imidacloprid suspension emulsion and preparation method thereof, prescription comprises following component: chlopyrifos 10%～30%, Imidacloprid 2%～10%, emulsifier 2%～10%, dispersant 0.05%～10%, antiprecipitant 0.05%～1%, antifreezing agent 1%～10%, wetting agent 0.5～1.5%, defoamer 0.1%～2%, solvent 5%～10%, water surplus (in gross weight 100%).Compared with prior art, this suspension emulsion low toxicity, good stability, cost is low, less energy consumption.But this medicine is to spray dispenser, and the medicine waste is large during use, when being used for the Corn Pests control since the later stage milpa higher, dispenser is inconvenient, is unfavorable for the control of the insects such as corn borer, aphid in corn later stage.
