Biological preparation for promoting tomato plant strain growth and preventing and controlling tomato late blight and preparation and application thereof

Abstract

The invention provides a biological preparation for facilitating the growth of tomato plants and preventing and treating late blight of tomatoes and a preparation method and application thereof, which relates to the technical field of biological pesticide. The biological preparation of the invention consists of 50g of raw duck yolk, 100 milliliters of edible vegetable oil, 100 milliliters of clean water and 62.5 milliliters of 1000 international unit/microlitre of Agritol. The preparation process of the biological preparation of the invention is the mixing of the four ingredients, which is characterized by convenient preparation, economic and effective, low cost, safe and no pollution. The preventing and treating effect of the biological preparation of the invention is averagely enhanced by 32.72 to 36.03 percent compared with the ordinary chemical preparations and 129.35 to 434.57 percent compared with the Agritol. Compared with clean water, the height-increasing rate of the plants is 6.19 to 14.19 percent.

Description

technical field [0001] The invention relates to the technical field of biological pesticides. In particular, it relates to a biological agent for promoting the growth of tomato plants and preventing and treating tomato late blight, and a preparation method and application thereof. Background technique [0002] The extensive and blind application of chemical pesticides in agricultural production has destroyed the ecological balance of farmland, seriously polluted the environment, and endangered the health of humans and animals. The 21st century is a century of green environmental protection and ecology. As human beings pay more and more attention to the protection of the environment and ecology, agricultural production adopts non-toxic, non-polluting, non-residue, non-killing natural enemies and beneficial organisms, suitable for pollution-free production requirements. It is of great significance to vigorously develop biological pesticides to meet the requirements of the tim...

Problems solved by technology

[0003] Although biopesticides have been widely developed and widely used, there are still problems in the research and development, production and application of biopesticides, such as high research and development costs, slow drug efficacy, short validity period, relatively narrow insecticidal antibacterial spectrum, and short-term control of diseases and insect pests. Problems and difficulties s...
