Description
Technical field
The present invention relates to composition pesticide and application thereof, specifically a kind of composition pesticide that is active ingredient with Zhongshengmycin, pyraclostrobin and fosthiazate, is mainly used in the control of crops soil-borne disease.
Background technology
Zhongshengmycin (zhongshengmycin): be a kind of novel agricultural antibiotic, has good activity to the bacterial disease of crops and some fungi venereal disease evil, has certain production-increasing function simultaneously.Its mechanism of action is by suppressing the peptide bond of pathogenetic bacteria protein to generate, finally causing bacterial death; There is strong inhibition effect to the sprouting of fungal pathogens spore, cause protoplasm cohesion in hyphal cell, change mycelium shape, play the effect of control fungal disease.
Pyraclostrobin (pyraclostrobin): belong to methoxy acrylic bactericide, the mechanism of action is mitochondrial respiratory function inhibitor, there is protection, treat, root out, permeate, strong in inhale and resistance of rainwater washing against effect.Fungicidal spectrum is wide, is widely used in preventing and treating the disease that wheat, barley, soybean, peanut, grape, vegetables, potato, banana, lemon, coffee, fruit tree, walnut, tea tree, tobacco, ornamental plants, lawn and other field crops are caused by the fungal pathogens of nearly all types such as sac fungi, basidiomycetes, imperfect fungus and oomycetes.
Fosthiazate (fosthiazate): belong to organic phosphates nematocide, the mechanism of action is suppress the synthesis of nematode acetylcholinesterase.Special efficacy is had to root-knot nematode, root-rot (short body) nematode, Cyst nematode, stem eelworm etc.Vegetables can be widely used in, banana, fruit tree, the crops such as medicinal material.
Soil-borne disease refers to lives in pathogene in soil as fungi, bacterium and nematode etc., the disease that will cause from crop root or stem infringement crop when condition is suitable for.Common soil-borne disease has: the club root of Cruciferae, stalk break, soft rot, the damping off of solanaceous vegetables, the crop such as melon, damping off, epidemic disease, root rot, fusarium wilt and verticillium wilt, the bacterial wilt and root knot nematode disease etc. of tomato, cucumber and sweet (peppery) green pepper.The root of the general damage to crops of soil-borne disease and stem, plant growth early stage, seedling will soon be dead, has a strong impact on crop production once there is disease, seedling root rot or stem rot is rotten dampings off; Plant growth deuterogenesis disease, general time underproduction 20-30%, serious time underproduction 50-60%, even has no harvest.In agricultural production, the various soil-borne diseases caused by pathogene such as fungi, bacterium and nematodes respectively often mix generation, but, the selectivity that current great majority prevent and treat the medicament of soil-borne disease is comparatively strong, cannot can both reach the object of effectively control to the various soil-borne diseases caused by pathogene such as fungi, bacterium and nematodes respectively simultaneously.Therefore, the use of single medicament obviously fundamentally can not solve causing harm of various soil-borne disease in crops, is also faced with the problems such as pathogen-resistance increases the weight of, use cost is high, environmental pollution is large.
Summary of the invention
The object of the invention is for above-mentioned Problems existing, a kind of composition pesticide containing Zhongshengmycin and pyraclostrobin and fosthiazate is provided, for preventing and treating the soil-borne disease in crops, a drug can solve the various soil-borne diseases caused by pathogene such as fungi, bacterium and nematodes respectively, simplify farming, save medicine cost, decrease environmental pollution, improve control efficiency.
Technical solution of the present invention: a kind of composition pesticide containing Zhongshengmycin and pyraclostrobin and fosthiazate, active ingredient is Zhongshengmycin, pyraclostrobin and fosthiazate, Zhongshengmycin percentage by weight is in the composition 0.5% ~ 15%, pyraclostrobin percentage by weight is in the composition 1% ~ 20%, fosthiazate percentage by weight is in the composition 5% ~ 35%, and all the other are allow in agricultural chemicals to use and acceptable auxiliary element.
Described auxiliary element comprises solvent, emulsifier, wetting agent, dispersant, antifreezing agent, thickener, disintegrant, binding agent, bleeding agent, defoamer, stabilizing agent, macromolecule cyst material, pH adjusting agent, synergist, liquid-carrier and solid carrier etc., it is all composition that is conventional in pesticidal preparations or permission use, be not particularly limited, concrete composition and consumption are determined by simple test according to recipe requirements.
Composition pesticide of the present invention can be prepared into the multiple application forms being applicable to agriculturally using, and reasonable formulation has suspending agent, aqueous emulsion, microemulsion, water dispersible granules, wetting powder, microcapsule suspending agent and granule.
The production technology of the various application forms of described composition pesticide all belongs to existing known technology, does not repeat them here.
The frequency of administration of the present composition and amount of application change with crops, insect, weather condition and have small variations, can by the object using suitable dosage reach effectively control
Compared with prior art, the invention has the advantages that:
1, Zhongshengmycin, pyraclostrobin and fosthiazate ternary built have significant synergistic function, the control efficiency significantly improved soil-borne disease in crops is used alone than single dose, expand control spectrum, a drug can solve the various soil-borne diseases caused by pathogene such as fungi, bacterium and nematodes respectively.
2, Zhongshengmycin, pyraclostrobin and fosthiazate ternary built, decrease Pesticide use amount, the service life reducing use cost, alleviate pollution to environment, delayed the drug-fast generation of pathogene, extended agricultural chemicals.

As can be seen from Table 2, when Zhongshengmycin, pyraclostrobin and fosthiazate are composite in a certain proportion of scope, synergism value (SR) is all greater than 1.5, shows synergistic function to bacterial wilt of tomato; Especially composite with 0.5:1:35 (by quality), synergistic function is the most remarkable, and synergism value (SR) is 3.82.Visible, Zhongshengmycin, pyraclostrobin and fosthiazate are composite has reasonability and feasibility.3, the composite Toxicity Determination to tobacco root-knot of Zhongshengmycin, pyraclostrobin and fosthiazate
Carry out statistical analysis with DPS statistical analysis software, calculate the EC of each medicament
50, adopt Wadley method, calculate the interactional synergism value of mixture (SR): when SR≤0.5, be antagonism; 0.5 < SR < 1.5 is summation action; SR>=1.5 are synergistic effect.
The composite Toxicity Determination result to tobacco root-knot of table 3, Zhongshengmycin, pyraclostrobin and fosthiazate

As can be seen from Table 3, when Zhongshengmycin, pyraclostrobin and fosthiazate are composite in a certain proportion of scope, synergism value (SR) is all greater than 1.5, shows synergistic function to tobacco root-knot; Especially composite with 0.5:1:35 (by quality), synergistic function is the most remarkable, and synergism value (SR) is 4.08.Visible, Zhongshengmycin, pyraclostrobin and fosthiazate are composite has reasonability and feasibility.
In sum, a kind of composition pesticide containing Zhongshengmycin and pyraclostrobin and fosthiazate provided by the invention, obvious synergy, a drug can solve the various soil-borne diseases caused by pathogene such as fungi, bacterium and nematodes respectively.Compared with existing single dose, the soil-borne disease successful in control crops improves, and the lasting period is long, to crop safety, is worth applying in agricultural production.
