تاثیر فرمولاسیون‌های مختلف آلومینیوم کلرید و آلومینیوم سولفات در کنترل بیماری کپک خاکستری میوه توت فرنگی

Due to the physiology of strawberry fruit and how it is harvested and stored and post-harvest pathogens, which are mainly Botrytis cinerea, it is of special importance in the production and sale of this product. The use of organic chemical fungicides has many negative effects on human health and the environment, creating resistance to plant pathogens, soil and groundwater pollution due to non-degradability and increasing costs. To replace organic fungicides with fungicidal minerals, two compounds of aluminum chloride and aluminum sulfate were formulated. In this study, two castor oils and flaxseed (10%), 20% (4%), 80 (6%) and PEG (5%) were used for formulation. Strawberry fruits are contaminated with spore suspension in the form of foliar application in three repetitions for each treatment and after 48 hours with minerals formulated in two doses of one per thousand and two per thousand for aluminum chloride and one per thousand and two. Per thousand were treated for aluminum sulfate and kept for 24 hours at 20 ° C, then for 72 hours at 10 ° C and after 24 hours at 25 ° C. The results of this study showed: aluminum chloride with a dose of two per thousand with 15% pollution and one dose per thousand with 20% pollution, aluminum sulfate with a dose of two per thousand 30% pollution and a dose of one per thousand with 50% pollution. The results showed that flaxseed and castor seed oil formulations were not significant. Thus, aluminum chloride with castor oil formulations and your seed with a concentration of two per thousand was the best treatment in controlling the disease after harvesting strawberry gray rot. To increase the efficiency of this mineral, research is underway to optimize the formulation.
