Sevin (carbaryl) is also a good choice as a inexpensive, broad-spectrum insecticide. It has a relatively short residual so toxicity degrades rapidly. It's been in use for vegetables for many decades so it is benign to humans but deadly to leaf chewing insects. Not a good choice for spider mite control so either a rotation with or, used in combination with Neem oil will cover a lot of bases. Since it degrades so quickly, it can require re-application every 2-3 weeks depending on insect pressure/populations but this also means it can be applied late in the growing season just prior to harvest. As always, read, understand and follow the label.
