SILWET L-77 is a unique surfactant designed to improve the spreading
and wetting properties of pesticide spray mixes. SILWET L-77 utilizes
unique organosilicone chemistry which provides the most complete
coverage possible. SILWET L-77 can improve cuticular penetration of
plant surfaces by the spray mix. Optimum application and resultant
effects can be influenced by many factors. Consequently, it is
recommended that careful observation of the spray deposit be made and
adjuvant rates adjusted accordingly. Applications should be made to
ensure thorough coverage without excessive run-off.

GENERAL PRODUCT INFORMATION
(1) SILWET L-77 contains organosilicone surfactants designed to
provide superior wetting and coverage.
(2) SILWET L-77 can improve water penetration of hard to wet soils
and provide more uniform distribution of applied moisture.
(3) SILWET L-77 is generally compatible with pesticides and
fertilizer solutions.
(4) SILWET L-77 may cause excessive foam if not properly added to the
spray tank. To minimize foam generation, add SILWET L-77 to the
tank after all other ingredients are added. If foaming is still
a concern, add an antifoaming agent, such as FOAMBUSTER or COMBAT
PLUS to the tank prior to adding SILWET L-77.
(5) Do not allow spray mixes containing SILWET L-77 to sit over 36hours.
