Malathion showed the greater impact on growth compared to Sevin. However, it could be recommended that for use of both pesticides on cucumber not more than the recommended dose should be applied. Snake cucumber (Cucumis melo L., var.

What can I use instead of Sevin?

The unfortunate thing about Sevin is that it is toxic to beneficial insects including honeybees. Another insecticide you can use instead is Bt (Bacillus thuringiensis). This insecticide, sometimes sold as Dipel, can be sprayed on the leaves in the area where they are feeding.
