Abstract
A kind of production method that is applicable to the bacteriostat and bi-germicide of preventing and treating bakanae disease of rice, be characterized in: earlier a certain amount of bronopol, tmtd, surfactant, methyl fiber system and potter's clay are pre-mixed in premixed device, pulverize through ultrafine crusher then, selection by winnowing, make granularity 〉=0.054mm aperture (300 order), after cyclone separator separates, enter in the finished product blender again, be finished product behind the mixing.The present invention has good control efficiency to bakanae disease of rice, and it is prevented and treated efficient and is not less than all bactericide at present, and to seedling stage seedling development obvious stimulation growth effect is arranged, but also characteristics such as it is low to have a cost, and period of storage is long.
Description
The present invention relates to a kind of control rice pest technical field, be specially adapted to the control of bakanae disease of rice.
Bakanae disease of rice is common fungal disease, and this disease all can take place from seedling stage to heading stage, is whole-plant disease.The characteristics of symptom are excessive growth.Seedling stage, sick seedling cauline leaf was slim and frahile elongated since second leaf, oyster, and it is normal that root system development is bad than strong height of seedling about 1/3rd, and the part rice seedling is withered in seedling stage, and not withered sick seedling can not rice transplanting.Diseased plant symptom after the rice transplanting is similar to seedling stage, and is withered successively to the preceding diseased plant of heading after the rice transplanting, even some plant heading is also shaky.Bakanae disease mainly is to carry disease germs based on seed, also can infect after seedling stage and the rice transplanting.In recent years, how northern China prevents and treats with how gloomy ammonium and evil seedling bactericide, begins to have obtained the better prevention effect, but because the continuous employing of the greater part, cause some some areas to produce pesticide resistance, and bactericide (Duosenan) is suspending agent, unsuitable stored for a long time.This bactericide has the effect that suppresses growth in earlier stage in seed germination in addition, thereby is necessary to develop a kind of even more ideal bactericide and substitutes bactericide (Duosenan).
A kind of bakanae disease of rice of more effectively preventing and treating of the confession that the objective of the invention is, and can have bacteriostat and bi-germicide and the production method thereof that promotes seed growth effect in the seed germination phase.
The object of the present invention is achieved like this: its production method is earlier a certain amount of bronopol, tmtd, surfactant, methylcellulose and potter's clay (or diatomite or boron cloud soil) to be pre-mixed in premixed device, pulverize through ultrafine crusher then, selection by winnowing, the particulate in granularity 〉=0.054mm aperture (300 order) is taken away by wind, after cyclone separator separates, enter in the finished product blender again, be finished product behind the mixing.
Wherein the percentage by weight of material input amount is:
Bronopol 5-20% tmtd 5-20%
Surfactant 3-10% methylcellulose 0.5-10%
Potter's clay (or diatomite or boron cloud soil) 40-86%
Above-mentioned surfactant is preferably selected lignosulfonates or neopelex for use.
The present invention has good control efficiency to bakanae disease of rice, and it is prevented and treated efficient and is not less than all bactericide at present, and to seedling stage seedling development obvious stimulation growth effect is arranged, but also characteristics such as it is low to have a cost, and period of storage is long.
The invention will be further described below by embodiment and experimental data.

The raw material specification requirement
Bronopol industrial goods 〉=95%
Tmtd industrial goods 〉=90%
Potter's clay industrial goods fineness 〉=0.054mm aperture (300 order)
2, technical process
(1), checks at first whether ultrafine crusher, blower fan, finished product blender and motor be normal;
(2), by above-mentioned prescription will quantitative bronopol, tmtd, calcium lignosulfonate (sodium) or neopelex, methylcellulose, potter's clay or diatomite or the native weighing of boron cloud accurate, and put into and carry out premix in the premixed device;
(3), premixed material at the uniform velocity added in the ultrafine crusher pulverizes, and regulate air quantity, (granularity 〉=0.054mm aperture [300 order]) that will reach certain longitude taken away by wind;
(4), after the feed separation of cyclone separator, enter in the finished product blender, mixed 1-2 hour, sample analysis, treat that material is evenly qualified after, the blowing packing is finished product.
3, following is that example is done an experiment contrast with prescription (1) and prescription (4).
Logical be that carry out in the experiment field of 103 rice varieties.
One, reagent agent
20% antibacterial pair of I wetting powder (prescription (1))
20% antibacterial pair of II wetting powder (prescription (4))
20% bronopol wetting powder
Two, experimental scheme
8 processing are established in test, randomized arrangement, and 3 repetitions, every processing gross area is 1.6 square metres (8 dishes).17054 strains of keeping a full stand of seedings of the every dish of seeding quantity 65 grams, every dish, bed soil adopts the modulator allotment of Yongji County agricultural center, and test is handled and is established:
Handle 200 times of liquid seed soaking of 1 20% antibacterial pair of I
Handle 250 times of liquid seed soaking of 2 20% antibacterial pair of I
Handle 300 times of liquid seed soaking of 3 20% antibacterial pair of I
