Tricyclic tin is the second pesticide to replace them. However, the tricyclic tin is imported, and Recent reports have led to mammalian brain tumor problems, we tested the amidine pesticides better. First, the phytotoxicity test Under different temperature conditions, the three varieties of different test results: The first test: temperature 21 ℃, 40% Acmicillin 500,1000 times, 40% Monoamidine 500,1000 times , Early on the local, Wenzhou mandarin no phytotoxicity.
