Abstract
The present invention discloses a garden nursery weed killer, which comprises the following raw materials by weight: 20-40% of metolachlor, 10-20% of pendimethalin, 2-8% of oxyfluorfen, and 43-58% of an auxiliary agent, wherein the use of the garden nursery weed killer can adopt preemergence spraying or postemergence killing. According to the present invention, the garden nursery weed killer adopts the vegetable oil as the solvent so as to provide characteristics of no pollution, neutral and slightly acidic pH value, excellent stability and good buffer property; the garden nursery weed killer does not contain harmful metals and hormone substances, such that the use is safe; the characteristic that the agent is only fixed on the surface soil layer (about 1-2 cm) and is not leached into the deep layer is adopted, such that the weed seeds capable of germinating in the surface soil layer are killed or inhibited, and the crop seeds can normally sprout and grow due to protection of the soil covering layer; and with the garden nursery weed killer, normal growth of crops can be ensured, the persistent period on the sandy soil ground can achieve 35-40 days, the persistent period on the clay ground can achieve 60-70 days, and 2-4 leaf stage weeds can be killed after sowing and seedling emergence.
Description
Technical field
The present invention relates to technical field of pesticide, relate in particular to a kind of Gardening Nursery weed killer herbicide and using method thereof.
Background technology
Weed killer herbicide claims again weedicide, is in order to eliminate or to suppress a class material of plant growth.Effect is subject to the impact of weed killer herbicide, plant and environmental condition three factors.By effect, be divided into go out natural disposition and selective herbicide, conventional kind is organic compound.Can be widely used in ground weeds, the assorted noxious plants such as tree of filling with, mix such as control farmland, orchard, floral nursery, grassland and uncultivated area, railway line, river course, reservoir, warehouse.
Weed killer herbicide refers to and can make weeds that withered medicament occurs up hill and dale or selectively.Sodium chlorate wherein, borax, arsenate, trichloroacetic acid have withered effect for the plant of any kind, but because these all have residual impact, so can not be applied in field.Selective herbicide particularly nitrophenol, chlorophenol, carbamic derivative majority is all effective.World Herbicide development is gradually steady, and main development is efficient, the kind of low toxicity, wide spectrum, low consumption, and the disposable treatment agent that environmental pollution is little becomes main flow gradually.It is higher that the same insecticide of weed killer herbicide, bactericide are compared the requirement of its operation technique.It is for the moment improper that insecticide, bactericide are used, and may just affect control efficiency.And weed killer herbicide improper use, and concerning the safety of plant growth.
In the weed killer herbicide that current Gardening Nursery is used, mostly exist drug toxicity large, affect plant strain growth or the effective problem such as weeding.
Summary of the invention
In order to solve the deficiency of the weed killer herbicide that existing Gardening Nursery uses, the object of the invention is to provide a kind of weed killer herbicide of Gardening Nursery safely and efficiently.
The technical scheme that the present invention takes is:
Gardening Nursery weed killer herbicide of the present invention is comprised of the raw material of following percentage by weight: isopropyl methoxalamine 20～40%, pendimethalin 10～20%, Oxyfluorfen 2～8%, auxiliary agent 43～58%.
Preferred: isopropyl methoxalamine 25～35%, pendimethalin 13～17%, Oxyfluorfen 2～8%, auxiliary agent 45～50%.
Described auxiliary agent is comprised of vegetable oil, surfactant and herbicide-safener.
Surfactant is stearic acid, neopelex, lauryl sodium sulfate, benzalkonium chloride, benzalkonium bromide, lecithin, fatty glyceride, fatty acid sorb is smooth or polysorbate in one or more; Herbicide-safener is N, N-diallyl-2, one or more in 2-dichloro acetamide, cyometrinil, oxabetrinil, fluxofenim, flurazole, fenchlorazole, fenclorim or MG191.
As one of preferred technical scheme: described weed killer herbicide is comprised of the raw material of following percentage by weight: isopropyl methoxalamine 25%, pendimethalin 17%, Oxyfluorfen 2%, vegetable oil 36%, stearic acid 10%, flurazole 10%.
As one of preferred technical scheme: described weed killer herbicide is comprised of the raw material of following percentage by weight: isopropyl methoxalamine 35%, pendimethalin 13%, Oxyfluorfen 8%, vegetable oil 24%, fatty glyceride 15%, N, N-diallyl-2,2-dichloro acetamide 5%.
As one of preferred technical scheme: described weed killer herbicide is comprised of the raw material of following percentage by weight: isopropyl methoxalamine 30%, pendimethalin 15%, Oxyfluorfen 5%, vegetable oil 30%, neopelex 5%, lecithin 5%, oxabetrinil 5%, MG191 5%.
The using method of weed killer herbicide of the present invention is as follows: before can seedling, spray or seedling after malicious micromicrofarad; Usage amount: seedling pre-treatment: a mu consumption 100ml is watered 30～40 kilograms of even spraying, seedling post processing: water or rain after, mu consumption 200ml and 60 jin of uniform stirrings of fine sand, spread fertilizer over the fields in field.
Gardening Nursery weed killer herbicide of the present invention is for ginkgo weeding.
There are following points for attention in weed killer herbicide of the present invention:
1, behind Kaifeng, should use as early as possible, otherwise may moisture absorption lump;
2, should be dried in cool place lucifuge place and preserve, the term of validity 2 years;
3, sooner or later use, select sunny calm weather as far as possible, before at 9 o'clock in the morning or after at 4 o'clock in afternoon, spray medicine, should not use in high light, high temperature, sleet sky;
4, in strict accordance with dosage explanation medication;
5, liquid is evenly sprayed on weeds blade face, notes avoiding nursery stock lobus cardiacus;
6, spray requires soil moisture content good during medicine, must first artificial moisture creating (pouring water) during soil drought, then herbicide spraying, while preventing soil drought, spray medicine generation poisoning;
Good effect of the present invention is as follows:
1, Gardening Nursery weed killer herbicide employing vegetable oil of the present invention is solvent, and pollution-free, pH value is neutral meta-acid, stability is superior, resiliency good; Not containing poisonous metal, not containing hormonal substance, use safety;
2, closed weeding before bud, medication before after planting emerging.Utilize medicament only to anchor at topsoil (approximately 1～2 centimetre) not to the characteristic of deep layer leaching, the weed seed that kills or suppress can sprout in topsoil, crop seed is because having overburden layer protection, normally germinating growth;
3, with respect to other closed weed killer herbicides, weed killer herbicide of the present invention can guarantee crop normal growth, and the lasting period can reach 35～40 days on sandy soil ground, in the clayed ground lasting period, can reach 60～70 days; After insemination and emergence, for 2～4 the leaf phase weeds also can kill.
