Abstract

The invention discloses a specific formula for bamboo locusts and belongs to the study field of agricultural science and the technical field of the study field in agriculture in tec. According to the specific formula, raw medicines including imidacloprid and efficient cyhalothrin are compounded into powder and are used for preventing and controlling the bamboo locusts which are pests of phyllostachys edulis forests, and the application dosage is 1.5-2.5g (being converted into 100% raw medicine content) per mu (unit of area); the pest-killing fast-acting property is excellent, nymphs of the bamboo locusts begin to be poisoned and die within 2 hours after application, and the control effect can is above 80% within 24 hours and is above 95% after two days; and the pesticide is relatively safe to human beings, livestock, natural enemies of the pests and other beneficial organisms, and the harm of a large amount of organic solvents to the environment is avoided. The specific formula for the bamboo locusts is simple in preparation process and low in cost and is suitable for popularization and application in mountainous water-shortage hilly lands in south.

Description

Bamboo locust proprietary formula

One, technical field

Ambit is agricultural science under this patent, and affiliated technical field is agricultural, and the segmentation field is plant protection.

Two, background technology

Ceracris kiangsui (Ceracris kiangsu Tsai) another name bamboo locust, locust, freshwater mussel mark, migratory locusts, the withered son of race, flower freshwater mussel mark, bramble finch, freshwater mussel chicken, it is the primary pest that China produces the bamboo district, be distributed in Anhui, on the south the Jiangsu various places, are the insects to China's bamboo producing region harm.Except the harm bamboo, but also hazard rice, corn etc. also take food the cauline leaf of the multiple kinds of crops such as vegetables, fruit, sweet potato when hungry.This worm is sudden strong, and the imago feeding blade is eaten into blade and incised, and when occuring greatly, the leaf of bamboo is suffered all, and as burning, when occuring greatly the leaf of bamboo is all eaten light, and the Hsinchu is killed once just withered, and strong bamboo is injured and does not send out in 2-3 bamboo shoot new.Ponding often in the killed bamboo pole, bamboo fibre is damaged, the forfeiture value.

1 year 1 generation of this worm, survive the winter with ovum 1-3 centimeters under the soil table, the hatching of next year 4-5 month hibernating egg, mid-June to early July begins to turn into adult, and late July to late August is the egg-laying period.The bamboo locust focuses mostly on greatly and lays eggs, and the nymph of a locust is unearthed and mostly can goes up bamboo after 24 hours and take food the leaf of bamboo.

Imidacloprid is the chloro nicotinic insecticide of in the world first exploitation, is the eighties Bayer A.G exploitation in last century, and it is researched and developed successfully has epoch-making meaning.Imidacloprid is a lot of in the trade name of China, clean such as the positive Imidacloprid in sea, one time, the aphid lice is clean, person who has rendered outstanding service, rehabilitation are many, must woods etc.Imidacloprid is chloro nicotinoids systemic insecticide, is the acting body of nicotinic acid nAChR ligands, disturbs the pest movements nervous system that chemical signal is transmitted malfunctioning, without the cross resistance problem.Be used for control sucking pest and resistant strain thereof.Imidacloprid is 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.Behind the insect contact medicament, the nervous centralis normal conduction is obstructed, and makes its paralysis dead.Quick-acting is good, higher preventive effect is namely arranged in 1 day behind the medicine, and residual life reached about 25 days.Drug effect and temperature are proportionate, and temperature is high, good disinsection effect.Be mainly used in preventing and treating sucking pest, such as aphid, plant hopper, aleyrodid, leafhopper, thrips; To coleoptera, diptera and lepidopterous some insect, also effective such as Lissorhoptrus oryzophilus Kuschel, rice leaf beetles, rice borer, leaf miner etc.But invalid to nematode and two spotted spider mite.Can be used for the crops such as paddy rice, wheat, corn, cotton, potato, vegetables, beet, fruit tree.Because its good interior absorption, be particularly suitable for seed treatment with spread the dispenser of granule mode.General mu is watered spraying or seed dressing with active ingredient 3-10 gram.Safety interval 20 days.Note protection during dispenser, prevent from contacting skin and suck medicinal powder, liquid, will in time wash clean exposure portion with clear water after the medication.Not with alkaline combined use of pesticides.Should not under strong sunlight, spray, in order to avoid reduce drug effect.

Gamma cyhalothrin is again trifluoro cyhalothrin, cyhalothrin, it is one of product the most representative in the pyrethroid pesticide, its mechanism of action mainly is to suppress the conduction at insect neural axon position, insect had walk quickly and keep away, knock down and feed toxic action, it is tagged and is the topmost mode of action.The gamma cyhalothrin insecticidal spectrum is wide, and activity is very high, and drug effect is rapid, and resistance of rainwater washing against after spraying, but use for a long time insect easily it to be produced resistance has certain preventive effect to insect and the evil mite of sucking mouth parts.

Gamma cyhalothrin is a kind of efficient, wide spectrum, quick-acting pyrethroid Insecticidal and acaricidal agent, without systemic action.The larva of the various pests such as Lepidoptera, coleoptera, Hymenoptera, orthoptera, coleoptera, Semiptera and tetranychid, rust mite, goitre mite, tarsonemid etc. there is good effect, forestry be mainly used to prevent and treat pine caterpillars, fall webworm, poplar caterpillar, pine sawfoy, spring looper etc. larva, also can be used to prevent and treat multiple earth's surface and public health insect.

Three, summary of the invention

On the basis of a large amount of indoor and woodland tests, having developed Imidacloprid and gamma cyhalothrin is main component, is aided with auxiliary agent and filler and is mixed with pulvis (being mainly used in southern mountainous terrain)

Its prescription consists of: Imidacloprid 0.2-0.6%, gamma cyhalothrin 0.1-0.3%, dispersant sodium lignin sulfonate 2-3%, filler talcum powder or kaolin complement to 100% (percentage in the prescription composition is weight ratio); The ratio of Diacloden and beta-cypermethrin is 2: 1.

Mu dosage 1.5-2.5 gram (being converted to the former medicine of 100% content), the consumption that dusts is 500-750g/ mu.

Four, description of drawings
