Crop Protection


As crops have evolved in this district, so has our expertise. Today, San Joaquin Sulphur Company remains an independent family owned ag supply company committed to our industry and our district. Our objective is to provide our customers with products and services that enhance the quality of their crop, safety of their workers and are environmentally sound.


Crop Protection from pests and diseases that can damage the fruit or the plant and from weeds that can rob valuable nutrients from your crop is vital. Rodents can eat away at the roots of trees, vines and row crops, eventually killing the plant.
