Try going to your local garden center anf getin some of this stuff called "Safer" Brand Insect Killing Soap w/ Seaweed Extract" You can use it all the way up to the day of harvest if you need too. All though I would stop using it for the last 7-10 days for best TASTE results. It doesnt leave any funny tase, but I do it just for the security of it. Hope this helps..........:thumbsup:
