Abstract:

Instability efficacy of Bio-pesticides influenced by the environment has been the consensus among scholars. This paper studied the effects of Imidacloprid and other 10 kinds of pesticides used commonly on B36（Bacillus Subtilis）WP against tomato gray mould. The results showed that 1.8% Avermectin EC mixed with the B36 WP can significantly increased the prevention and control efficacy of B36 WP against tomato gray mould at 2.59 percentage points and 5.84 percentage points, respectively. Mancozeb 80% WP mixed with the B36 WP decreased control efficacy at 1.77 percentage points and 5.82 percentage points, respectively. The other pesticides cannot affect significantly the efficacy of B36 WP against tomato gray mould.
