Q.

What dose per litre of water for bacillus thuringiensis

Zone Zone? AquItaine, France | ECWinBordeaux added on July 15, 2015 | Answered

I have about 20 box shrubs in my garden. Overnight I found that two of them have been defoliated by caterpillars, so I am very anxious to treat the apparently unaffected bushes. I have a packet of Bt weighing 30 grams. My question is, how many liters will this make up? Your help will be of great assistance. Thank you.

Use the mixing directions that come with the package you have bought.
Mixing ratios will differ from product to product.

Always use a test area of your plant and wait 24 hours.
