Is preventative spraying ok for disease and pests?
IÂve had tomatoes in the garden a few years now and always end up getting diseased foliage and bug damage. Does it make sense to periodically spray for disease and pests before they start in? After I notice issues I spray with Ortho Garden Disease or Bug be Gone. Last year lost most of my cuks and squash to cucumber beetles who infected my plants, tomatoes looked lousy from blight (at least I think it was blight). I watch the tomatoes and spray after I see insect damage, but in my yard there seems to always be some insect attacking the gardens. Is there a recommended routine for preventative spraying? First year with Heirlooms and want to give them a fighting chance.
