Micro nutrient deficiencies such as boron, damage to flowers from insects (thrips, mites, tarnish plant bug, etc.) and botrytis may cause misshaped fruit.
Usually occurs during weather extremes or very early in spring during frost/freeze conditions as well as cold wet weather.
Micro nutrient deficiencies such as boron, damage to flowers from insects (thrips, mites, tarnish plant bug, etc.) and pathogens (botrytis) may also cause pollination problems. Examine plants closely for insects and pathogens also use tissue testing to check nutrient status to rule these out.
Control pest and correct nutrient problems if present. Provide good frost protection and adequate irrigation when needed.
