Abstract
The present invention relates to a kind of soil fungicides composition of fluorine-containing ether bacterium acid amides.Its active ingredient is fluorine ether bacterium acid amides, dislikes mould spirit and garlic oil.It may be used for the fusarium wilt of preventing and treating the various vegetables such as cucumber, tomato, eggplant, capsicum, also can be used for control cotton wilt and seedling stage root disease.The present invention by fluorine ether bacterium acid amides, dislike mould spirit and garlic oil composite, not only increase sterilization virulence, delay pesticide resistance, reduce chemosynthesis medicament consumption, also because garlic oil has higher sterilization virulence, in soil, stifling bactericidal action is strong, and thus synergy is more remarkable.
Description
Technical field
The present invention relates to pesticide field, particularly relate to a kind of soil fungicides composition and use thereof of fluorine-containing ether bacterium acid amides.
Background technology
Fluorine ether bacterium acid amides (LH-2010A), is a kind of amide-type wide-spectrum bactericide, has very high biologically active to Oomycete fungal germ, has protection and therapeutic action.Fluorine ether bacterium acid amides has stronger interior absorption.Absorb by cauline leaf, conducted by plant lower to upper part direction, distribute to whole strain crop along plant xylem.
Disliking mould spirit is a kind of systemic fungicide, has interior suction and conduction, is again a kind of soil disinfectant simultaneously, to various plant soil-borne diseases: pythium spp, seedling rotten bacterium, sickle-like bacteria, rhizoctonia, root shell bacterium etc. have good control efficiency.
Garlic oil is the important substance extracted from garlic, and main component is pi-allyl propyl disulfide compound, diallyl disulfide, diallyl trisulfide, allicin etc.It is a kind of broad-spectrum antiseptic material, has activating cell, promotes that energy produces, increases the multiple pharmacological functions such as antibacterial and anti-virus ability, quickening metabolism, fatigue-relieving.
The ground family crops such as cucumber fusarium axysporum [Fusariumosysporum (Schl.) f.sp.cucumerinumOwen] main harm cucumber, sponge gourd, watermelon, muskmelon, cucurbit, wax gourd.Along with the development of the facilities vegetable such as greenhouse, booth, especially for many years continuous cropping, the generation of protecting field fusarium wilt is day by day serious.There is the multiple agricultural chemicals preventing and treating fusarium wilt on the market at present, but by fluorine ether bacterium acid amides, dislike mould spirit and garlic oil and carry out composite fusarium wilt of preventing and treating and have not been reported.
Summary of the invention
The object of the present invention is to provide a kind of soil fungicides composition of fluorine-containing ether bacterium acid amides, to improve the control efficiency to vegetables fusarium wilts such as cucumber, delay the resistance of pathogen to systemic fungicide, reduce cost accounting.
Based on above-mentioned purpose, the soil fungicides composition of a kind of fluorine-containing ether bacterium acid amides provided by the invention, it is characterized in that, its active ingredient by fluorine ether bacterium acid amides, dislike mould spirit and garlic oil forms, described fluorine ether bacterium acid amides, the weight ratio of disliking mould spirit and garlic oil are 10 ~ 30:5 ~ 20:5 ~ 20, active ingredient total content is 20 ~ 70%, and all the other are auxiliary agent and filler.
Preferably, described fluorine ether bacterium acid amides, the weight ratio of disliking mould spirit and garlic oil are 10 ~ 30:10 ~ 20:10 ~ 20.Preferred, described fluorine ether bacterium acid amides, the weight ratio of disliking mould spirit and garlic oil are 20:10:10.
The present invention can use wetting agent and filler traditionally above-mentioned microbicide compositions to be processed into wetting powder or water dispersible granules.Wherein, filler is selected from least one in white carbon, kaolin, diatomite, attapulgite, potter's clay and clay.Wetting agent is selected from lauryl sodium sulfate, sodium lignin sulfonate, at least one pulled open in powder.
Present invention also offers the purposes of the soil fungicides composition of above-mentioned fluorine-containing ether bacterium acid amides, described microbicide compositions for preventing and treating the fusarium wilt of the various vegetables such as cucumber, tomato, eggplant, capsicum, also can be used for control cotton wilt and seedling stage root disease.
Present invention also offers the method using fusarium wilt such as vegetables such as the control of above-mentioned composition pesticide cucumber, tomato etc., it is characterized in that, in planting seasons such as cucumber, tomato, capsicum, eggplants, use fluorine ether bacterium acid amides, dislike mould spirit, garlic oil wetting powder or water dispersible granules, impose on plantation ditch or plant in plant hole, then transplant or sow, effective ingredient consumption is 250g ~ 375g/667m
2.
Fluorine ether bacterium acid amides of the present invention, dislike mould spirit co-toxicity result of the test to cucumber fusarium axysporum mixed with garlic oil as indicated with 1.Can be found by table 1, fluorine ether bacterium acid amides, dislike that mould spirit is mixed with garlic oil has very high virulence to cucumber fusarium axysporum, each proportioning synergistic effect is remarkable.When fluorine ether bacterium acid amides, dislike mould spirit and garlic oil composite with 4:2:1 ~ 2:2:4 time, reach 140.2 ~ 171.9 to the co-toxicity coefficient of cucumber fusarium axysporum, synergy is very remarkable.Fluorine ether bacterium acid amides, to dislike mould spirit mixed with garlic oil, not only increases sterilization virulence, and because of garlic oil, to fumigate bactericidal action strong, thus Synergistic sterilizing effect is more remarkable.
Table 1 fluorine ether bacterium acid amides, dislike mould spirit co-toxicity to cucumber fusarium axysporum mixed with garlic oil
The present invention is proved by field trial, 50% wetting powder made with the present invention or water dispersible granules (fluorine ether bacterium acid amides: dislike mould spirit: garlic oil=20:20:10), vegetables fusarium wilt such as control booth vegetable or open country cucumber, tomato, capsicum, eggplant etc., consumption is 500g ~ 750g/667m
2, effective ingredient consumption 250g ~ 375g/667m
2spread fertilizer over the fields when the vegetable transplanting such as cucumber, tomato in transplanting cave (ditch), 85.2 ~ 93.7% are reached to the control efficiency of fusarium wilt, survival rate of seedlings 100%, fusarium wilt harm can be controlled completely, also can prevent and treat the multiple sprout term diseases such as homochronous root rot, damping off, vegetable growth is had no adverse effect.
The invention has the beneficial effects as follows: microbicide compositions provided by the invention, by fluorine ether bacterium acid amides, dislike mould spirit and garlic oil composite, not only increase sterilization virulence, delay pesticide resistance, reduce chemosynthesis medicament consumption, also because garlic oil has higher sterilization virulence, in soil, stifling bactericidal action is strong, and thus synergy is more remarkable.The using value of this composition pesticide in vegetable disease control is large, and economic and social benefit is remarkable.
