There are a couple of new products approved by the Organic gardening groups for use the same day as harvest. Unfortunately, I don't have the names handy, but will repost them soon. I bought them from Johnny's Seeds.
The first is a water soluable version of BT. This eliminates some of the difficulty handling and applying a dust and provides uniform coverage. Those who dust recognize how sometimes the volume applied is not very uniform.
The second product is a water soluable combination of Diatomaceous Earth and botanic grade pyrethrin. It has the same advantages as above. Pyrethrin is the oil from the Pyrethrin chrysanthemum. Pyrethrin combined with the synergist piperonyl butoxide is extremely common on the market place, but is not organic garden approved because of the piperonyl butoxide. (jury still out)
Another technique is to use row covers. These products let most of the light through, but if used properly prevent access by many bugs.
Keep in mind that using the terms, pesticide or chemical, is politically correct mumbo jumbo. Non-toxic is an oxymoron. Everything is made of chemicals. There are no tests to determine whether something is a pesticide. A pesticide is anything used to kill a bug. Anything SOLD as a pesticide must conform to EPA laws which require safety data etc. Home made remedies are still pesticides, even if they are made of seemingly harmless ingredients. Many home made concoctions are more toxic than commercially available products.
The advantage to using a commercial product versus a home made concoction is that the toxicity data is known, mixing percentages/application instructions are included and information about which insects are affected is on the label.
Most soaps have pesticidal qualities. There are insecticidal soaps available, but they are a bit pricy. The advantage to using them is the label instructions. I have heard of 1 tbs dish soapn per gallon for treating some insects.
