Hocking International Laboratories

Hocking International Laboratories manufactures spray adjuvants — the products that decide whether an expensive herbicide or fungicide actually stays on the leaf and gets absorbed, rather than beading up and running off.
Our Hocking range covers EMPRO methylated seed oil (MSO) in 2.5 gal, EMPRO spreader/sticker, and EMPRO 90/10 and 80/20 non-ionic surfactants in 1 gal and 2.5 gal.
Always read and follow the product label and the tank-mix partner's adjuvant requirements. Browse Hocking International adjuvants and surfactants below, with free shipping on qualifying orders.
