| It was aimed to evaluate the efficiency of spreading drops in cassava leaves of Solutions with Biological insecticides and adjuvants in different concentrations. The experimental design was completely randomized in a factorial 2 x 3 x 5, with four replications. The treatments consisted in the preparation of solutions of two biological insecticide Bacillus thuringiensis (500 g ha- 1, Dipel WP® - 32,0 g kg-1) and baculovirus (0,41 g ha- 1) , with addition of three adjuvants (Mineral oil-Nimbus®, vegetable oil- Aureo® and glycerine- Hygrogem® , soybean biodiesel byproduct ) in five concentrations (0,0; 0,2; 0,4; 0,6 and 0,8 % v v- 1), cassava leaves comes the variety 'IAC 90'. The spreading of the drops (13μL) of the solutions were evaluated in adaxial and... |
