PyGanic Crop Protection EC 5.0 works via contact activity only. It kills insects only at the time of application. Complete spray coverage is essential. Spray mix should be buffered to pH 5.5-7.0 to avoid rapid product degradation. UV sensitive, so apply late in the day. Repeat applications are usually needed. Rotate with insecticides with different MOA to avoid insect resistance to pyrethrins.
