AI Technical Summary

Technical Problem

The existing technology is difficult to effectively prevent and treat chili grey mold, especially in low temperature and high humidity conditions, the use of chemical pesticides has drug resistance problems and pesticide residue problems, so green biological control methods need to be found.

Method used

A Lecanicillium attenuatum strain Lat-ivf2024 and its fermentation broth were used as biofungicides, and the leaves of peppers were treated by spraying to inhibit the growth of Botrytis ale.

Benefits of technology

In the greenhouse potted plant test, the condition index of pepper gray mold in the Lat-ivf2024 fermentation broth treatment group dropped to 43.70, which achieved a 54.26% prevention effect compared with the condition index of 95.56 in the control group, significantly reducing the disease symptoms of pepper.

Abstract

The invention discloses a strain of Lecanococcus attenuata for preventing and controlling pepper gray mold. In a test of preventing and controlling pepper gray mold, the fungus has a greenhouse potted control effect on Botrytis cinerea when treated with Lat-ivf2024 strain fermentation liquid. The pepper gray mold disease index of the treatment group dropped to 43.70, compared with the disease index of the control group of 95.56, and the control effect was 54.26%. The Lecanococcus attenuata can be used to prevent and control pepper gray mold caused by Botrytis cinerea. The strain plays a certain role in promoting the development of new biological pesticides to solve the harm of gray mold in pepper production.
