A Preliminary Study on The Prevention and Control of Plum Fruit Brown Rot by"Meshroom Treasure A+B"
In order to clarify the efficacy of"Meshroom Treasure A+B"in the control of plum fruit brown rot and its effect on fruit quality,we conducted an efficacy test in 2024.The results showed that the efficacy of"Meshroom Treasure A+B"against plum fruit brown rot was 78.10%,which was 5.99%,14.92%,6.34%,13.39%higher than that of control agents 40%chlorofluorfenoxazole,12%benzyl-flumioxazole,24%cyprodinil and 70%thiophanate-methyl in that order,but the differences were not significant.Fruit quality measurement showed that the highest single fruit weight was 197.70 g in the"Meshroom Treasure A+B"treatment,which was 12.98%,4.34%,10.38%and 17.97%higher than that of control agents 40%chlorofluorfenozole,12%benzyl-flumioxazole,24%cyprodinil and 70%thiophanate-methyl in that order.However,the contents of soluble sugars,titratable acid and vitamin C were relatively low compared to other treatments.After 7 days of storage at room temperature,the preventive effect of"Meshroom Treasure A+B"against brown rot of plum fruit reached 100%,which was 50%,25%,50%and 75%higher than that of the control agents 40%chlorofluorfenpyrazole,12%benzyl-flumioxazole,24%cyprodinil and 70%thiophanate-methyl in that order.The hardness of fruit treated with"Meshroom Treasure A+B"was 5.25 N,which was 3.22,4.86,4.27 and 1.45 times higher than that of control agents 40%chlorofluorfenoxazole,12%benzyl-flumioxazole,24%cyprodinil and 70%thiophanate-methyl,respectively.The results showed that"Meshroom Treasure A+B"has good preventive effect against plum fruit brown rot in the field and storage period,and can improve the weight and hardness of fruit,increase the yield and prolong the shelf life of commodities.
