Effects of PBO and flusilazole on calyx shedding rate and fruit shape of Laiyang Chili
Different concentrations of PBO,flusilazole(Flu)and their mixtures were sprayed during the flowering period to observe the effects on calyx shedding rate and fruit shape of Laiyang Chili.The results showed that PBO,Flu and their mixtures could improve the calyx shedding rate of Laiyang Chili.The calyx shedding rate was 18.87%~21.63%for spraying PBO 100~400 times a-lone,25.31%for spraying Flu 6 000 times alone,and 39.76%~51.90%for spraying a mixture of PBO 100~400 times and Flu 6 000 times,which was significantly higher than that of each individual treatment.The method for calyx removal with pharmaceuticals is simpler and easier than manual calyx cutting,and saves labor cost.However,the fruit shape index and single fruit weight was decrease.
