Abstract
The invention discloses a kind of composition pesticide containing Benfuracard micro, its active ingredient is Benfuracard micro and tioxazafen, and both mass ratioes are 1：50‑50:1.The present composition has obvious coordinative role to nematode, the control of nematode available for the plants such as vegetables, fruit tree, oil crops, cereal crops, sugar crop, medicinal plant, cotton crudefiber crop, gardening gardens class plant and place.
Description
Technical field
A kind of composition pesticide of the present invention, more particularly to a kind of composition pesticide containing Benfuracard micro and its
The application of crops root-knot nematodes is prevented and treated, 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, problems be present in the chemical agent for preventing and treating root-knot nematode：(1) residues of pesticides are high, and (2) input cost is high, and (3) are anti-
Effect is not notable enough, and (4) have much room for improvement to the yield and quality of crop.
Benfuracard micro is carbofuran low toxicityization derivative, and insecticidal effect is close to carbofuran, but toxicity only has carbofuran
1/10th.It is a kind of wide spectrum, systemic insecticide, suitable for rice, corn and soybean, potato, sugarcane, cotton, vegetable
The crops such as dish, fruit tree, prevent and treat various pests.
Tioxazafen, chemical name：3- phenyl -5- (thiophene -2- bases) -1,2,4- oxadiazoles.Meng Shan is opened for 2008
The non-stifling property nematode agent of hair, because its is more environmentally friendly, use is safer, and the influence to people is smaller, and the ideal for being described as lythidathion is replaced
Dai Pin, indoor and field experiment show, the reference product of the performance of the new nematicide equivalent to or better than current commercialization.
It is reported that tioxazafen is to the soy bean cyst roundworm of soybean, root-knot nematode, kidney shape nematode, and the pratylenchus on corn, root knot
The phytopathy original nematode such as nematode, long line worm, kidney shape nematode, root-knot nematode on cotton is respectively provided with fabulous bioactivity.
Up to now, there is not yet Benfuracard micro and the open source literature of tioxazafen compoundings.
The content of the invention
It is an object of the invention to provide a kind of composition pesticide containing Benfuracard micro, help to delay nematode to produce
Resistance, improve prevention effect, reduce effective ingredient consumption and use cost etc..
Inventor after a large amount of Seiving Tests, is having been surprisingly found that Benfuracard micro and tioxazafen by certain ratio
After example mixture, there is notable synergistic effect to plant root-knot nematode, with obtainable can be prevented and treated using only single active component
Effect is compared, and is used in mixed way and more preferable prevention effect is provided to parasitic nematode.
The present composition has synergistic function, and is therefore particularly suitable for preventing and treating plant nematode, especially
In vegetables, fruit tree, medicinal plant, cereal crop, oil crops, sugar crop, cotton crudefiber crop, gardening gardens class plant
Parasitic nematode.
Composition pesticide provided by the invention, it is characterised in that：Contain active ingredient Benfuracard micro 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 vegetables, and (such as cucumber, beans, tomato, potato and Curcurbitaceae are planted
Thing), it is banana, pseudo-ginseng, coffee, corn, fruits, rice, wheat, barley, oat, rye, soybean, peanut, ornamental plant, sweet
Harmful organism on the plant such as 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
Kind (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 the present composition is used to prevent and treat the oil crops such as vegetables, fruit tree, medicinal plant, soybean and peanut, standing grain
The nematodiasis of cereal, rice, wheat, cotton, flowers etc., as cucumber root-knot nematode, tomato root-knot eelworm, capsicum root-knot nematode,
Citrus root-knot nematode, soy bean cyst roundworm, peanut root-knot nematode etc..
The present composition can be prepared into the formulation of suitable agricultural use with known method, active ingredient in preparation
Total content is 5%-80%, and remaining is pesticide adjuvant composition.
The composition pesticide of the present invention can be formulated as spraying or carrying out soil or the particle of seed treatment after being available for dilution
Agent, water dispersible granules, suspending agent, microemulsion, aqueous emulsion, microcapsule suspending agent and suspension seed-coating agent.
Preparation is prepared in a known way, such as is 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 when 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, had the beneficial effect that caused by composition pesticide of the present invention：(1) compared with single dose, synergy is bright
It is aobvious, improve prevention effect；(2) field dosage can be greatly decreased, reduce the possibility for causing poisoning, poisoning, reduce life
Production and use cost, and can effectively reduce environmental pollution and residues of pesticides；(3) mechanism of action of active ingredient is mutual not in composition
It is identical, the single selection pressure to nematode is reduced, is advantageous to overcome nematode resistance to produce and delay the drug-fast generation of nematode
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：Benfuracard micro compounds the Toxicity Determination to cucumber root-knot nematode with tioxazafen
Experiment

30d is cultivated under the conditions of 50%.Each to repeat the basin of random searching 4, each processing amounts to 16 basin cucumber of investigation.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 forms 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.
