| This project aim to evaluate the efficiency of spreading droplets in solutions with biological insecticide and adjuvants in leaves of different varieties of cassava. The experimental design was entirely randomized in a factorial 3x7, with four replications. It was performed three solutions with biological insecticide, with and without adjuvants: Bacillus thuringiensis (500 g ha-1, Dipel WP® - 32.0 g Kg-1), B. thuringiensis (500 g ha-1) + glicerine (0.5% v v-1, Hygrogem® byproduct from the soybean biodiesel) and B. thuringiensis + mineral oil (0.5% v v-1, Nimbus®) and were evaluated in seven varieties of cassava (Baianinha, Cascuda, Fécula Branca, IAC 118, OlhoJunto, Peru and IPR-União). The spreading of droplets of the solutions was evaluated on adaxial... |
