Description

Strawberry powdery mildew control agent and its manufacturing method and use {A FUNGICIDE FOR CONTROLLING STRAWBERRY POWDERY MILDEW AND ITS PREPARATION METHOD AND USE THEREOF}

The present invention relates to the field of agrochemicals, and more particularly, to a strawberry powdery mildew control agent, and a method for manufacturing and use thereof.

Strawberry powdery mildew is an important disease commonly seen during strawberry production, and since the prevalence and frequency of occurrence and serious damage are severe, after strawberry powdery mildew, the production is generally reduced by 20% to 30%, and in severe cases by 50%, even with no harvest at all. It severely affects the production and quality of strawberries. Strawberries can develop strawberry powdery mildew from seedling stage to fruit maturity stage, and due to continuous cultivation in house for many years, pathogens accumulate year after year in pergola and soil, so strawberry powdery mildew develops early and is serious. The ventilation and light transmittance of the house facilities is poor, the cultivation density is too large, and the temperature in the house is suitable and the humidity is high, which makes it more favorable for the occurrence of strawberry powdery mildew. In addition, strawberries do not have salt-alkaline tolerance, so if management is not suitable, plant growth is inhibited and powdery mildew occurs easily, and varieties suitable for picking such as "Hongan" and "Janghee" are more sensitive to strawberry powdery mildew.

Strawberry powdery mildew is caused by the fungus Ascomyceae, subfamily Sphaerotheca aphanis, which is an obligate parasite. Powdery mildew was first discovered in strawberries at the House of Shenyang Agricultural University in China in 1959 (“Strawberry Powdery Mildew Research Exhibition,” Yubak et al., Hanam Agricultural Sciences, 2007, 2nd term, pages 20 to 22), and Yangseo in 2013. et al. observed the microstructure of strawberry powdery mildew using a scanning electron microscope and found that both mycelium and spores were attached to the surface of both mature and old leaves of infected plants to grow (“Using a scanning electron microscope to detect strawberry powdery mildew) Observation", Yangseo et al., Journal of Electron Microscopy, Vol. 32, vol. 3, pp. 260-265). In this study, pathogens were present in young, unaffected leaves of strawberry plants in this study, but the number of mycelium was small. Strawberry powdery mildew mycelia were all increased on the leaf surface of different nodes according to the leaf growth process. It was also found that the morphology was enriched.

In current production, prevention is done with "insurance drugs" and chemical agents are mainly used after the onset of the disease. Although chemical agents have a certain control effect, due to the massive use of chemical pesticides, various kinds of harmful germs develop resistance to drugs and are controlled. At the same time as the difficulty increases, it also harms the plant itself and remains in the strawberry, which is harmful to human health and pollutes the environment.
