If there is a risk of phytotoxicity, which formulation should you choose?

Choosing a wettable powder formulation is particularly appropriate when there is a risk of phytotoxicity. Wettable powders are designed to be mixed with water and they create a suspension of fine particles that can disperse evenly. This results in a more controlled release of the active ingredient that can mitigate the potential for phytotoxic effects on plants.

Wettable powders typically adhere better to plant surfaces and avoid the rapid uptake of chemical substances when compared to other formulations. This slow release reduces the likelihood of causing damage to the plant tissues, making it a favorable option in situations where sensitivity of the target plants is a concern.

Moreover, wettable powders can be formulated to ensure that the active ingredients are delivered in a manner that respects the plant's tolerance levels. The other formulations, such as emulsifiable concentrates and liquid suspensions, may result in quicker absorption and, therefore, an increased risk of phytotoxicity due to their concentrations and modes of action. Granules, while useful for certain applications, often do not provide the same level of control in situations where plants are at high risk for damage.
