Hello Mr. Cho
In your book, to make 500L of pesticide your recommended dosage is:
JWA 3-15L
JS 0.5-2L
JHS 5-30L
JWA 3-5L, for use in chemical pesticides.
My question is, have the above doses been tested in all climates (subtropical and tropical)?
The answer will be very much appreciated and I will use it in practice. Thanks.
