Try to bag plum, apricot this morning and found out very small amount of fruits worth of bagging, most,95%, has some kind of scars on the fruits. I bagged about 3,4 perfect fruits on each tree. This spring I sprayed more than I did previous year. I sprayed at petals fall , Triazicide, 7~10days later, Malathion. I am not sure the bugs are extra hungry this year , different bugs,or my pesticides are no longer potent. I have asked about potency of pesticides/fungicide on other thread, but no one seems provide an good enough answer that I can use. My triazicide was purchased two years ago, the mfg date is 2016 on the bottle. I used extra tbs when I mixed it with water this year.
My peaches on other hand, are very clean this year,no single bite on any peaches so far and pray to keep this way. Although, this year peaches didn’t set as many fruits as normal years, but this is OK I don’t have to thin them.
Interestly, one of my apricot that was grafted on a branch of large peach tree has perfect fruits. None of the fruits on this apricot branch have been bitten by any bugs. While a grafted J plum just about couple of feet way only has one good fruit left. I am puzzled
