What issues may arise from mixing incompatible pesticides?

Increased effectiveness against target pests.
Decreased need for agitation in the tank.
Loss of effectiveness, phytotoxicity, increased hazard, and clogging of equipment.
More efficient dispersion and coverage.

The correct answer is: Loss of effectiveness, phytotoxicity, increased hazard, and clogging of equipment.

Mixing incompatible pesticides can lead to a loss of effectiveness, causing the pesticides to become less potent and less effective in controlling pests. This can result in increased costs and a need for multiple applications. Additionally, there is a risk of phytotoxicity, which can damage the plants being treated. There is also an increased hazard, as mixing incompatible pesticides can create harmful chemical reactions. Finally, there is a potential for equipment clogging, which can result in delayed or incomplete application of the pesticides. Therefore, it is important to carefully research and follow proper mixing instructions to avoid these potential issues.
