Own azoles alcohol and bacillus subtilis Recompounded pesticide
Affiliated technical field
The present invention relates to Recompounded pesticide, particularly a kind of Recompounded pesticide that rice sheath blight disease and false smut is had certain effect.Be specially own azoles alcohol and bacillus subtilis Recompounded pesticide.
Background technology
Rice sheath blight disease in the Asia, the country of America, African rice cultivation generally takes place.All there is distribution in each rice district of China, but takes place generally with rice district on the south the Changjiang river, and early, middle and late rice all can be taken place, and causes that ripening rate and thousand kernel weight significantly reduce, even the plant lodging is withered.Short-stalked variety is injured heavier.Because wide, the popular frequency height of area takes place, loss often surpasses rice blast, the serious field piece underproduction about 60% due to it.False smut is blue or green powder disease again, and paddy rice is how susceptible in heading, flowering stage, forms the disease fringe, and along with the close grain of paddy rice type kind large tracts of land is promoted, fertilizing amount constantly increases, and planting density strengthens, and causes rice green smut to be on the rise.False smut takes place not only to have a strong impact on rice yield when serious, and pollutes rice.False smut also can produce toxin and directly be detrimental to health.Therefore it is very necessary to prevent and treat rice green smut.Nearly 2 years of false smut is in rising trend, and late growth stage of rice is too light green luxuriant, meets the growth of rainfall and the favourable germ of high humidity flowering stage again, brings out this disease easily.Paddy rice cut, full heading time temperature suit, and rainfall is on the high side, help false smut and contaminate harm.
All the time, the control of rice sheath blight disease is based on the farm antibiotics jinggangmeisu, but jinggangmeisu just was extensive use of since the seventies, the time limit is longer, and dosage progressively increases, and resistance strengthens, it is slow that medication number of times and dosage have been turned over several times and preventive effect, in case outburst is difficult to control in a short time; And the control of false smut mainly relies on organic class agricultural chemicals, and this pesticide residue is big, influences the healthy of people.Therefore exploitation has instant effect, mutual supplement with each other's advantages to the composite agricultural chemicals of human and environment close friend's biopesticide and low toxicity chemical bactericide, and market potential and social value are huge.
Summary of the invention
The present invention seeks to be to solve the problems referred to above that exist in the existing technology, design provides a kind of own azoles alcohol and bacillus subtilis Recompounded pesticide of high-efficiency broad spectrum, and its toxicity is low, effective, cost is lower.
The technology of the present invention solution is: own azoles alcohol content is 0.1%~20.0%, and the bacillus subtilis bacterial content is 1.0~1000.0 hundred million/gram, and other functional aid, filler or carrier supply 100%.

Own azoles alcohol (hexaconazole) is azoles fungicide; the mechanism of action and characteristics are sterol methylation inhibitors, destroy and stop the biosynthesis of the cell membrane important composition composition steroid ergosterol of germ, and leading the system cell membrane can not form; make germ death, have interior suction, protection and therapeutic activity.Suitable crop is fruit tree, cereal class, ornamental plants etc.; under recommended dose, use; to environment, crop safety; can effectively prevent and treat son and assist disease due to bacterium, basidiomycetes and the imperfect fungus, especially assist bacterium, the microbial disease of banded sclerotial blight such as powdery mildew, rust, brown spot, banded sclerotial blight etc. that excellent protection and eradicant action are arranged basidiomycetes and son.Be known crop, can buy by Jiangsu Lianyungang Liben Agro-chemical Co., Ltd..
Bacillus subtilis is a plant resource quasi-microorganism bactericide, and this product is a biologic product, and bacterial classification obtains from soil or axis separation, is brevibacterium.Rice sheath blight disease, false smut there are preventive effect preferably, have to regulate and activate plant growth, alleviate the effect of germ harm such as bacterial leaf streak of rice, bacterial leaf-blight, bakanae disease, be known substance, can buy by sky, Wuhan a species of orchid biotechnology Co., Ltd.
Described own azoles alcohol can be made into wetting powder, soluble liquid, microemulsion, suspending agent, water dispersant, granule etc. with the bacillus subtilis Recompounded pesticide, adds function corresponding auxiliary agent, wetting agent, diffusant, filler or carrier etc. in the promptly former medicine.Also can be made into missible oil: add organic solvent and emulsifier in the promptly former medicine; Also can be made into aqueous emulsion: add organic solvent, cosolvent, wetting agent, diffusant, antifreezing agent, emulsifier and water etc. in the promptly former medicine.
Described own azoles alcohol and bacillus subtilis Recompounded pesticide, co-toxicity coefficient reaches 92~156, its fungicidal spectrum is wide, quick-acting and lasting effect is better, and cost is lower, descends 30% than the mu of own azoles alcohol with cost, be applicable to the control of diseases such as paddy rice, cotton, vegetables, fruit tree, especially false smut and the banded sclerotial blight to paddy rice has the better prevention effect, increases production and improves productivity obviously, and rice growth is had no adverse reaction.Proportioning in patent application of the present invention is weight content.

Measurement result shows that the co-toxicity coefficient of embodiment one is 92; The co-toxicity coefficient of embodiment two is 114; The co-toxicity coefficient of embodiment three is 124; The co-toxicity coefficient of embodiment four is 139; The co-toxicity coefficient of embodiment five is 156, and all the other co-toxicity coefficients have obvious synergistic effect all greater than 100 except that embodiment one.Each proportioning synergy is obvious, consider from the lasting effect of reagent cost and medicament, with embodiment five as preferably.
Control efficiency result of the test through the field to false smut and banded sclerotial blight shows: 2.5% own azoles alcohol, 10,000,000,000/gram bacillus subtilis wetting powder mu with 30 gram medicines after inspection in 10 days, control efficiency is respectively 89%, 82%, every mu of medication of 10% own azoles alcohol missible oil 40 grams, control efficiency is respectively about 80%, 10,000,000,000/gram bacillus subtilis mu restrains with 30, control efficiency is respectively 66%, 59%, and visible 2.5% own azoles alcohol 10,000,000,000/gram bacillus subtilis wetting powder control efficiency is the most desirable.The above-mentioned medicament of respectively handling does not have sterile reaction to rice growth, and can promote the paddy growth volume increase in varying degrees, and the rice is doing well, and the leaf look delicate and pretty, and the later stage heading is neat.
List is 3.5 yuan with 10% own azoles alcohol missible oil mu medication 40 gram pesticide cost, restrains composite dose with 2.5% own azoles alcohol 10,000,000,000/gram bacillus subtilis wetting powder mu with 30, and pesticide cost is about 2.5 yuan, descends 30% than single with own azoles alcohol mu cost.
