Abstract
The present invention relates to a nimbic oil water emulsion. It is characterized by that it contains (wt%) 1-49% of nimbic oil and 50-98% of water, and is prepared by mixing them. Said invented nimbic oil water emulsion can be used for controlling root-knot eel-worm in the soil, and can obtain obvious effect, and its cost is low.
Description
Technical field
The present invention relates to prevent and treat Nim oil-water emulsion of root-knot nematode in the soil and uses thereof.
Background technology
China is large agricultural country, in agricultural planting industry, and the cereal crops paddy rice of not only causing harm of the root-knot nematode in the soil, also very serious to causing harm of economic crops such as fruit, tealeaves, tobacco, vegetables, medicinal material, already bring tremendous loss for agricultural planting.In the process of this insect of control, organic phosphors such as a large amount of now use chemical pesticide furans pellets and Nemacur, phoxim, acephatemet; Celfume, the contour malicious agricultural chemicals of nemagon; And biological pesticide avermectin.Although bringing into play important effect in the process of chemistry that these are a series of and biologic product root-knot nematode in control soil, but its residual in soil and also very serious to the pollution of causing harm and air, water source being caused of user, the more important thing is that above-mentioned most of agricultural chemicals is not only residual in a large number in soil, its residual also very serious in the crop of plantation, and the healthy of the edible eater that this residue arranged that directly cause harm.Use existing chemical pesticide and Avermectins biopesticide, action target spot is single, and the drug resistance of target worm constantly strengthens, and forms the increasing vicious circle of dosage, has also influenced the outlet of China's agricultural planting product simultaneously.
The existing insecticide made from neem oil has safety preferably, but is the plant insecticide of natural degradation, not caused harm by insect but be used for the protective plant acrial part basically.Do not see the experiment report and the application of the control Nim oil-water emulsion that is useful on root-knot nematode in the soil.
Summary of the invention
The purpose of this invention is to provide a kind of root-knot nematode that can prevent and treat in the soil, and the good Nim oil-water emulsion of control efficiency.
Nim oil-water emulsion of the present invention is pressed following preparation:
After neem oil 1～49%, water 50～98% mixing, add an amount of protectant such as potassium sorbate, citric acid, TBHQ (ditert-butylhydro quinone) etc. and make.
Nim oil-water emulsion of the present invention is used for preventing and treating the soil root-knot nematode.
It below is the experiment effect that preparation of the present invention is used for preventing and treating the soil root-knot nematode.
1, laboratory experiment:
The amount of trying to please is 4 in the flowerpot of 2.5KG, with the laterite of taking from underground 1.8m, fill flowerpot respectively, microscopy does not find that root-knot nematode is arranged in the soil before the dress basin, larva and ovum, pH value is 5.5, but soil moisture is held tight water outlet, keep 22～25 ℃ of temperature, each basin is inoculated 100 of Meloidogyne incognita 2 instars respectively after three days, inoculation degree of depth 5cm diluted Nim oil-water emulsion by 1: 500 concentration two basins wherein after three days, and every basin evenly waters two basins that contrast with dilution 200ml and evenly pours into clear water in basin, microscopy after 48 hours does not find in the flowerpot of dispenser in the target worm contrast basin and detects the target worm.Back each field planting cucumber seedling in 4 basins moved into the greenhouse 10 days, extracts cucumber its root is checked, naked eyes no abnormality seen, microscopy find that control group has nematode, and the dispenser group is not found.
Laboratory experiment shows that Nim oil-water emulsion has good killing action to root-knot nematode in the soil.
2, outdoor experiment:
Choose season plantation eggplant, and the plot of the incidence of disease 100%, 200 strains of field planting eggplant, per 20 strains are a contrast, when field planting, water the 250ml clear water and make normal root water by 20 strains, the soup 250ml that waters 250 times of concentration every 20 strains does the totally 10 groups of contrasts of normal root water, temperature of shed is controlled at 18～28 ℃, humidity 80%, soil moisture fully guarantee the plant strain growth needs, after 10 days, near 5～10cm soil microscopy every group selection 5 strain main roots, with the soup is the root-knot nematode that do not see of normal root water, and the clear water group is all found root-knot nematode, concurrent existing a spot of ovum.After 20 days, randomly draw 5 strains for every group and observe, the symptom reflection of being injured of the existing root of clear water group shows and the contrast of dispenser group that plant strain growth is slow, and here leaf-shrinkage withers, dispenser group riotous growth.
Test shows: Nim oil-water emulsion has fine preventive and therapeutic effect to root-knot nematode in the soil.
Nim oil-water emulsion of the present invention acts on that the mechanism of action of root-knot nematode is respectively in the soil: poison, reduce the enteron aisle vigor, and growthing lag, food refusal suppresses to lay eggs, therefore, and long-term the use, target insect species can not develop immunity to drugs.Existing chemistry and biological root-knot nematode prevent and treat 350～30 yuan of preparation cost per mus, only be 5 yuan and use preparation of the present invention to reach same every mu of use cost of control efficiency, help Nim oil-water emulsion of the present invention preventing and treating in the process of root-knot nematode in soil and promote the use of.The present invention opens as insecticide for neem oil and has kept away purposes more widely.
Embodiment
Embodiment 1:
After neem oil 1%, water 98% mixing, add 1% protectant citric acid, make Nim oil-water emulsion.
Embodiment 2:
After neem oil 49%, water 50% mixing, add 1% protectant potassium sorbate, make Nim oil-water emulsion.
Embodiment 3:
After neem oil 30.5%, water 69% mixing, add 0.5% protectant TBHQ, make Nim oil-water emulsion.
The using method of root-knot nematode in the Nim oil-water emulsion control soil: after above-mentioned preparation is diluted with water to finite concentration (generally adding 300～800 times of water) water or flood irrigation, determine diluted concentration according to the extent of injury of insect pest.
Claims (3)
1. use Nim oil-water emulsion for one kind, it is characterized in that containing neem oil 1～49%, water 50～98%, form through being mixed with.
2. Nim oil-water emulsion according to claim 1 is characterized in that can adding an amount of protectant such as potassium sorbate, citric acid, TBHQ in preparation.
3. Nim oil-water emulsion as claimed in claim 1 is characterized in that being used for preventing and treating the root-knot nematode of soil.
