Apples and pears do well with plastic zip lock bags. Even when I cut off the bottom cornersquite wide, bugs do not bother to fly in from bottom up.
However, this year, I got too much moisture trapped in some bags, causing my pears to have rough skin like russeting. I took bags off all pears after a month. By then, pears have expanded so fast crushing bug eggs along the way. I left bags off some apples, no bug damage so far.
Stone frruit is another story. Plastic bags tend to cause rot. Other organza or perforated bags can't protect against OFM and PC that can lay eggs through the bags. Only Clemson bags work but putting them on is not my strength
