Influence of K Salts in Enhanced Herbicide Activity

Maximize process of pest control reducing loss in the agriculture process is fundamental.The aim this research was to achieve a different way to increase the herbicide activity, using potassium salts.Some experiments were conduct to analyze the efficiency of salts in enhanced the activity of two selected herbicides (paraquat and bromoxynil).Firstly, we checked the effects of chaotropic and kosmotropic potassium salts and their capability to cause damage in the foliar tissue, and made a dosage adequate to avoid these undesirable effects.Later on, we analyze the physiological impairments due salts using PAM-Fluorecence techniques, employing different kind of arrays to verify, the response and ability to increase the real damage in foliar tissues.The best performance was obtained with multiple droplets applied 48 hours earlier than herbicides, promoting an increase of 2 times more efficacy, for paraquat and bromoxynil. Highlighted Conclusions1.There is interaction between K salt and herbicides.2. Microencapsulated herbicides consist in a strategy to combine with K salts.
