Abstract
The invention discloses a kind of nematicidal composition containing carbosulfan, its active ingredient is carbosulfan and tioxazafen, and both mass ratioes are 1:50‑50:1；The present composition has obvious synergistic function to nematode, the control of nematode available for the plants such as oil crops, cereal crops, sugar crop, cotton crudefiber crop, gardening gardens class plant and place.
Description
Technical field
The present invention relates to a kind of nematicidal composition, more particularly to a kind of nematicidal composition containing carbosulfan and
It prevents and treats the application of crops nematode, belongs to technical field of pesticide.
Background technology
Plant nematode mainly includes：Meloidogyne (Meloidogyne), kidney shape turbatrix
(Rotylenchulus), cyst roundworm (Heterodera (Heterodera)), root spot nematode (Pratylenchus
(Pratykenchus)).Eelworm harm influences the absorption of Plant To Nutrient and moisture, returns phytopathogen invasion and provides just
Profit.At present, there is problems with the chemical agent of preventing and treating root-knot nematode：(1) residues of pesticides are high, and (2) input cost is high, and (3) prevent
Effect is not notable enough, and (4) have much room for improvement to the yield and quality of crop.
Carbosulfan is carbofuran low toxicity derivative, and insecticidal effect is close to carbofuran, but toxicity only has carbofuran
1/10th.It is a kind of wide spectrum, systemic insecticide, it is adaptable to paddy rice, corn and soybean, potato, sugarcane, cotton, fruit tree
Deng crop, various pests are prevented and treated.
Tioxazafen, chemical name：3- phenyl -5- (thiophene -2- bases) -1,2,4- oxadiazoles are Meng Shan all 2008 years
The non-stifling property nematode agent of exploitation, because its is more environmentally friendly, using safer, the influence to people is smaller, is described as the ideal of lythidathion
Substitute.Indoor and field experiment shows that control of the performance equivalent to or better than current commercialization of the new nematicide is produced
Product.It is reported that tioxazafen is to the soy bean cyst roundworm of soybean, root-knot nematode, kidney shape nematode, the pratylenchus on corn,
It is living that the phytopathy original nematodes such as kidney shape nematode, root-knot nematode on root-knot nematode, long line worm, cotton are respectively provided with fabulous biology
Property.
Up to now, the open source literature of carbosulfan and tioxazafen compoundings is not yet inquired.
The content of the invention
It is an object of the invention to provide a kind of nematicidal composition containing carbosulfan, and help to delay line
Worm produces resistance, improves prevention effect, reduction effective ingredient consumption and use cost etc..
Inventor after a large amount of Seiving Tests, is having been surprisingly found that carbosulfan and tioxazafen by certain ratio
There is notable synergistic effect to Plant nematode after example mixing.
The present composition has synergistic function, and is therefore particularly suitable for preventing and treating plant nematode, especially
Parasitic nematode in cereal crop, oil crops, sugar crop, cotton crudefiber crop, gardening gardens class plant.
The nematicidal composition that the present invention is provided, it is characterised in that:Containing active ingredient carbosulfan and
tioxazafen.Both mass ratioes are 1:50-50:1, preferred mass ratio is 1:30-30:1, more preferably mass ratio is 1:10-
10:1。
The present composition can also prevent and treat various crops such as corn, paddy rice, wheat, barley, oat, rye, soybean, flower
Harmful organism on the plant such as life, ornamental plant, sugarcane, cotton and in seed.
The present composition is particularly suitable for preventing and treating plant nematode, such as Pratylenchidae (Pratykenchus
Spp), Radopholus similis Throne (Radopholous similis), fuller's teasel Ditylenchus dipsaci (Ditylenchus dipsaci), partly wear
Pierce nematode (Tylenchulus semipenetrans), Heterodera kind (Heterodera spp.), ball Heterodera
Plant (Globodera spp.), Meloidogyne kind (Meloidogyne spp.), kidney shape turbatrix kind (Rotylenchulus
Spp.), Aphelenchoides kind (Aphelenchoides spp.), minute hand Turbatrix kind (Longidorus spp.), sword nematode
Category kind (Xiphinema spp.), burr Turbatrix kind (Trichodorus spp.), Bursaphelenchus kind
(Bursaphelenchus spp.)。
It is preferred that by the present composition be used for prevent and treat the oil crops such as soybean and peanut, Cereal, paddy rice, wheat, cotton,
The nematodiasis of flowers etc., such as citrus root-knot nematode, soy bean cyst roundworm, peanut root-knot nematode.
The present composition can be prepared into active ingredient in the formulation of suitable agricultural use, preparation with known method
Total content is 5%-80%, and remaining is pesticide adjuvant composition.
The nematicidal composition of the present invention can be formulated as being available for of spraying or progress soil or seed treatment after dilution
Granula, water dispersible granules, suspending agent, microemulsion, aqueous emulsion, microcapsule suspending agent or suspension seed-coating agent.
Preparation is prepared in a known way, for example, prepared by the way that active component is mixed with solvent and/or carrier, if desired
If use other pesticide adjuvant compositions such as emulsifying agent and dispersant.
Insecticide-applying way can take spraying, pouring root, soak seed, get rid of and apply, spread fertilizer over the fields, ditch spread, spreading manuer in holes, preferred ditch during preventing and treating nematode
Apply, spread manuer in holes, the soil treatment such as pouring root or leaching root, seed soaking, seed pelleting processing.
Compared with prior art, what nematicidal composition of the present invention was produced has the beneficial effect that：(1) compared with single dose, synergy
Substantially, prevention effect is improved；(2) field dosage can be greatly decreased, reduction causes poisoning, the possibility poisoned, reduction
Production and use cost, and it is effectively reduced environmental pollution and residues of pesticides；(3) mechanism of action of active ingredient is mutual in composition
Differ, reduce the single selection pressure to nematode, be conducive to overcoming nematode resistance to produce and delaying the drug-fast production of nematode
Raw speed；(4) nematicidal composition has good preventive effect to all kinds of nematodes.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, present invention specific examples below
Illustrate, but the present invention is only limited to absolutely not these examples.
The synergistic function of the present composition can pass through following experiment explanation：
Assays Example：Carbosulfan compounds the Toxicity Determination to peanut root-knot nematode with tioxazafen
Experiment
Subjects：Meloidogyne incognita (Meloidogyne incognita)
Evaluation method is pot-culture method.The pieces of an egg aseptic water washing of picking root-knot nematode, is placed in culture dish from Roots of Peanut
Wet filter paper on, add 20ml sterilized waters, hatch at 20 DEG C -25 DEG C, obtain age consistent 2 instar larvaes, diluted with sterilized water
To 200/ml.2 instar larvaes are inoculated with the leaf phase of peanut two, using root injection method, take 5ml nematodes inoculation liquid to inject rhizosphere soil
It is interior, 24h soil conservations 70%-80% humidity after inoculation.It is standby after peanut inoculation root-knot nematode.

30d is cultivated under the conditions of 50%.Each to repeat the basin of random searching 4, each processing amounts to investigation 16 potted flowers life.Grade scale is in
Magnificent people's republic's national standard《Pesticide field efficacy medicine test criterion (one)》.
Diseased plant stage division is as follows:
0 grade:Root system is without insect gall；
1 grade:Root system has a small amount of small insect gall；
3 grades:2/3rds root systems are covered with small insect gall；
5 grades:Root system is covered with small insect gall and has secondary insect gall；
7 grades:Root system formation fibrous root group.
Computational methods：
The expection effect (i.e. theoretical prevention effect, %) of mixture of active principles determined using Colby formula and with observation
To effect compare：
Colby formula：E=X+Y-X*Y/100
E：When active components A concentration is a in composition, compositions contemplated when active component B concentrations are b is imitated
Power,
X：Effect when active components A dosage is a,
Y：Effect when active component B dosages are b.
When the prevention effect observed exceedes expected preventive effect, explanation has synergistic effect.
