Description
Technical Field
The invention relates to the technical field of pesticides, and particularly relates to a pesticide-fertilizer composition and a preparation thereof.
Background
The pathogenic bacteria are microorganisms existing all the time in the growth process of crops, and the pathogenic bacteria can be enriched in soil in continuous cropping planting or rotation planting, so that the pathogenic bacteria are more obvious in continuous cropping planting. Although the enrichment of pathogenic bacteria of the same species is slightly less, the species of pathogenic bacteria are more. The pathogens present on crops are in large part derived from the soil and therefore treatment of soil pathogens is of considerable interest in preventing pathogens from harming crops.
Fludioxonil is a common compound for preventing and treating crop pathogens, and inhibits the transfer of glucose phosphorylation and the growth of mycelium by influencing the activity of histidine kinase related to an osmotic pressure regulation signal, thereby causing the death of pathogens.
Azoxystrobin is a broad-spectrum pesticide and is common in compound pesticides. Researches show that azoxystrobin can inhibit mitochondrial respiration to cause death of cell nucleus and further generate bacteriostatic action, so that azoxystrobin has the advantage of wide action range.
The two using modes of the existing degerming pesticide are generally two, namely foliage spraying and tree smearing, and are characterized in that the degerming pesticide is prepared into liquid for use, and is attached to the surfaces of leaves or trees to further act on pathogenic bacteria; both modes can not effectively act on pathogenic bacteria of crop roots, so that the effect is poor in the aspect of preventing crop diseases.
Fertilizers have irreplaceable effects during the growth of crops, and can affect not only the yield of crops, but also the structure of soil. The humic acid is an organic substance which is obtained by fermenting remains of animals and plants and widely exists in the nature, can provide a large amount of organic matters for the growth of crops, and is beneficial to the absorption and utilization of the crops. In addition, humic acid can improve soil structure and can act for a long time as compared with chemical raw materials, and thus, in recent years, humic acid has been increasingly used.
The degerming pesticide is generally used as a quick-acting bactericide when being used, so the degerming pesticide has the characteristic of short action time in the current use mode, is usually required to be used for multiple times, is difficult to act on pathogenic bacteria in soil for a long time if the current degerming pesticide is applied to the soil, and obviously has the defects of time and labor waste when being applied to the soil by multiple times of slotting, so the pesticide charge composition which is synchronously applied with fertilization and can inhibit bacteria for a long time has important significance.
