Diseases Methyl bromide is used as a method of control for several diseases found in squash production. One of the more prevalent diseases found in squash is damping-off. Damping-off can be caused by Phythium spp. and Rhizoctonia solani. This disease can affect young plants causing the plant to collapse at the soil line, and it can cause seeds not to germinate (Florida Plant Disease Control Guide, 1993). A cultural method of control for damping-off includes avoiding planting in soils that have unfavorable moisture and temperature regimes. The chemical control methods for damping-off are listed in Table 4.10. Table 4.10. Chemicals for the control of damping-off.
