bug spray for bell peppers
What is a good bug spry for protecting bell peppers from bugs? I have found that this year many of my pepper plants are being eaten by some bug. Although I check the plants 3 or 4 times per week I have not seen the bugs so I cannot identify them. However, many of the tiny buds ( where the flower turns into a pepper ) are now just stubs so some bug or bugs must be eating them. I tried spraying with Bug Be Gone to no avail.
We do not recommend using any insecticidal sprays unless a specific pest insect has been identified. Pepper plants sometimes drop their flower buds and fail to develop fruits if the plants are stressed. https://extension.umd.edu/growit/poor-blossom-and-fruit-set-vegetables We do not recommend any spray as a repellent.
What would cause the pepper plants to be stressed? Although one is only 3 feet high because it is in partial shade, the rest range from 4 to 6 feet high and are dark green. Does the dark green color mean that too much nitrogen in the soil is causing stress? I can't think of anything else that would cause stress.
Too much nitrogen could be one of the factors in poor fruit development. Poor fruit set can be caused by prolonged dry or wet soil conditions, very high (can kill pollen) or very low temperatures, excessive shade, excessive nitrogen fertilization, and hot, dry winds. Also, failure to harvest crops regularly can signal plants to slow down flower and fruit production.
