I grow Hazera’s Felicity cherry variety in an open field. Recently, the Bemisia tabaci population is much higher than in previous seasons.
10% of my plants show minor TYLCV symptoms, and generally the fruit color is less red (a bit orange). Is this normal?
Under very high TYLCV inoculation, even tolerant varieties can manifest symptoms. It is very important to minimize the stress caused by the Bemisia tabaci by using pesticides. Optimal growing conditions will allow plants to recover from minor symptoms. The orange color is probably due to physical damage caused by the Bemisia tabaci. Bringing down the Bemisia tabaci population and ensuring optimal growing conditions can reduce the problem.
