Description
Technical Field
The invention belongs to the technical field of pesticide preparation, and particularly relates to a bactericide composition, a preparation method and application.
Background
The bacterial leaf blight of rice is one of three traditional diseases in China, the yield of the rice can be reduced by 10% -20%, and the serious field can reach more than 50% and even be completely harvested. Spraying chemical agents is still the main emergency measure for preventing and treating the bacterial leaf blight of rice at present. However, in the past two decades, due to the occurrence of bacterial blight in China, the attention of various communities to the disease is slightly insufficient, and the development of oral medicaments is almost stopped. At present, the varieties of the agents for preventing and treating bacterial blight are few, the agents mainly rely on zinc thiazole, thiacetone and other heavy metal agents for preventing and treating bacterial blight, and the selectable agents are extremely limited. As is known, in the process of applying the bactericide to prevent and treat crop diseases, a single-variety or single-action mode chemical bactericide is continuously used for a long time at a high dose, pathogenic bacteria are easy to generate resistance, the pesticide effect is weakened until the prevention and treatment effect on the diseases is lost, and finally, the chemical bactericide is inevitably used in an excessive amount to harm human health and ecological environment. Therefore, under the current situation that the rice bacterial blight is heavy in soil, the research and development of a novel action mechanism medicament is urgent.
The reasonable compounding of the bactericide has the advantages of expanding the prevention and control range, improving the prevention and control effect, delaying the generation of the drug resistance of diseases and the like, and is the most rapid and effective method for solving the problems.
The Bordeaux mixture is a protective bactericide and can inhibit spore germination or hypha growth of pathogenic bacteria by releasing soluble copper ions. Under acidic condition, the copper ions can also solidify the cell plasma of pathogenic bacteria to play a role in sterilization when released in large quantity. Under the conditions of high relative humidity and dew or water film on leaf surfaces, the pesticide effect is good, but the pesticide damage is easy to generate on plants with poor copper tolerance. Has long lasting period, is widely used for preventing and treating various diseases of vegetables, fruit trees, cotton, hemp and the like, and has excellent effect on leaf diseases of downy mildew, anthracnose, potato late blight and the like.
Mineral oil is mainly used as an insecticide in agriculture, and disease control is rarely reported. The insect killing mechanism is that mineral oil forms an oil film on the surface of a worm body or an egg shell and enters air valves and air pipes of larvae, pupae and adults through capillary action to suffocate insect pests; the ovum killing purpose is achieved by penetrating the ovum shell and interfering the metabolism and the respiratory system action of the ovum.
At present, no report that the Bordeaux mixture and the mineral oil are compounded and used for preventing and controlling the bacterial blight of rice exists.
Through the above analysis, the problems and defects of the prior art are as follows:
the pesticide for preventing and treating the bacterial blight of the rice is few, and the conventional sterilization composition has poor synergistic sterilization and prevention effects and large pesticide consumption.
