Abstract

The invention discloses a biological pesticide suitable for strawberry powdery mildew and a preparation method of the biological pesticide. Aiming at the characteristics of the strawberry powdery mildew and the action mechanisms of various biological agents and herb extracts, the biological agents with different efficacies and characteristics, such as trichoderma, allicin, bacillus subtilis, low-poly-D glucosamine hydrochloride, a thunder god vine extract and a tomatidine extract, are reasonably screened and compounded. The invention further discloses an effective preparation method. The prepared biological pesticide is good in action effect on strawberry powdery mildew, nontoxic, harmless, ecological and environmentally friendly; the use amount, the medication frequency and the medication cost are significantly reduced; and the biological pesticide is convenient to prepare, long in storage time and very high in practical value.

Description

technical field [0001] The invention relates to strawberry planting techniques, in particular to a biological pesticide suitable for strawberry powdery mildew and a preparation method thereof. Background technique [0002] Strawberry powdery mildew is one of the important diseases of strawberries, which can occur throughout the growing season of strawberries. The disease at the seedling stage causes the quality of seedlings to decline, and it is difficult to survive after transplantation. After the fruit is infected, the quality of strawberries is seriously affected, resulting in a decline in the yield. Under suitable conditions, it can develop rapidly, spread into disasters, and cause serious losses. [0003] Biopesticide refers to the use of living organisms (fungi, bacteria, insect viruses, genetically modified organisms, natural enemies, etc.) or their metabolites (pheromones, auxins, sodium naphthalene acetate, 2,4-D, etc.) to kill agricultural pests Or inhibited prepa...
