Summary
The effect of three different concentrations (half, equal and twice of the recommended dose) of three herbicides (trifluralin, dinitramine and fluometuron) usually used to control cotton weeds on the development of Rhizoctonia disease in cotton was studied. Trifluralin and dinitramine at the lower concentrations increased pre- and/or post-emergence damping off. Both herbicides at these concentrations increased the saprophytic activity of the fungus, while they did not affect the susceptibility of the cotton plants. Fluometuron at the highest concentration used was highly phytotoxic and increased the post-emergence damping off. This chemical at the recommended dose caused a drastic reduction in the pre- and post-emergence damping off caused byR. solani. Fluometuron at this concentration decreased both the susceptibility of the host plants and the saprophytic activity of the fungus.
