Embodiment 1

[0021] A bactericidal composition for rice bakanae disease, the dosage form is wettable powder, and the specific proportions of the components are as follows: trifloxystrobin 42%, tebuconazole 14%, traditional Chinese medicine bactericidal ingredients 24%, sodium hexametaphosphate 4%, Chaku powder 3%, laureth polyoxyethylene ether 3%, and the rest is supplemented with light calcium carbonate to 100%. Among them, the traditional Chinese medicine bactericidal ingredients are a mixture of Coptis chinensis, white peony root, madder, plantain, southern crane lice, and pumpkin seeds .

[0022] The preparation method is as follows: thoroughly mix the above components, pulverize with a sand mill and pass through a 300-mesh sieve to obtain the wettable powder of the bactericidal composition.

Embodiment 2

[0024] A bactericidal composition for rice bakanae disease, the dosage form is a suspension concentrate, and the specific proportions of the components are as follows: 20% trifloxystrobin, 15% tebuconazole, 15% bactericidal ingredients of traditional Chinese medicine, and alkylphenol polyoxyethylene ether Phosphate ester 2%, saponin powder 2%, glycerol 3%, turpentine 2%, benzoic acid 1%, and the rest is supplemented with water to 100%. A mixture of comfrey, shijunzi and pumpkin seeds.

[0025] The preparation method is as follows: thoroughly mix the above-mentioned components, and pulverize through a sand mill until the diameter of 90% of the medicament particles is less than or equal to 5 μm, so as to obtain the bactericidal composition suspension.

Embodiment 3

[0027] A bactericidal composition for rice bakanae disease, the dosage form is water-dispersible granules, and the specific proportions of each component are as follows: trifloxystrobin 14%, tebuconazole 28%, traditional Chinese medicine bactericidal ingredients 18%, sodium lignosulfonate 2 %, Tween 60 2%, glycerin 3%, polyvinyl alcohol 2%, alkylphenol polyoxyethylene ether 1%, and the rest is supplemented with diatomaceous earth to 100%. A mixture of gardenia, red vine, genus chinensis, and southern crane lice.

[0028] The preparation method is as follows: fully mix the above components, prepare the mother powder by pulverizing, mix the mother powder and an appropriate amount of aqueous solution evenly, shear at high speed and grind with a sand mill, then perform fluidized bed granulation, dry and sieve, The water-dispersible granules of the fungicidal composition can be prepared.

Abstract

The invention discloses a rice bakanae disease sterilization composition and an application thereof. The sterilization composition is obtained through perfectly combining different action mechanisms of various pesticides with traditional Chinese medicines with sterilizing and pest dispelling effects and using proper assistants and carriers as auxiliary materials. Compared with traditional pesticides, the sterilization composition has the following advantages: 1, high efficiency, low toxicity, low residual, good quick effect, long persistent period and environmental protection are realized; 2, the sterilization composition has no interaction pesticide resistance with traditional rice bakanae disease control mainstream pesticides; 3, all pesticides have compatibility, and the sterilization composition has substantial synergism, improved sterilization activity, reduces the dosage of single bactericides, and saves the pesticide use cost; 4, addition of the traditional Chinese medicines reduces the pesticide resistance risk of pathogens to the chemical pesticides, is in favor of keeping the pathogen sensitivity and delays the pesticide resistance of pathogens to single doses in the formula; and 5, the sterilization effect is substantial, damages of diseases to production of crops are reduced, and the output and the quality of agricultural products are improved.

Description

Technical field [0001] The present invention relates to the technical field of pesticides, and in particular to a bactericidal composition for rice bakanae disease and its application. Background technique [0002] After bakanae disease infects the rice body, a large amount of gibberellin is synthesized, which suppresses the abscisic acid content in the body, causing the rice plant to elongate rapidly and lose control until it turns yellow and finally dies. The harm is serious. Although there are many varieties of pesticides currently used for rice bakanae disease, they can only soak the seeds to prevent the disease, but cannot spray the seedlings to cure the disease, and do not have multiple functions. Even after soaking the seeds, during the germination process, if there are low temperatures, rainy days, and the time out of the cellar is extended, even only 0.1% of the germs can multiply rapidly and become seriously infected. Therefore, the existing pesticides have poor c...
