表面活性剂L-77高效有机硅表面活性剂，能够极大的降低水的表面张力,表面活性剂L-77有机硅溶液可轻易湿润几乎所有种类的叶面,相对于传统助剂,显著提高了在靶标生物的覆盖面.同时，表面活性剂L-77有机硅助剂具有极强的耐水冲刷及渗透能力。是拟南芥及其它作物常用的转基因用表面活性剂。
Surfactant L-77 is a unique surfactant designed to improve the spreading and wetting properties of pesticide spray mixes. Surfactant L-77 utilizes unique organosilicone chemistry which provides the most complete coverage possible. Surfactant 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) Surfactant L-77 contains organosilicone surfactants designed to provide superior wetting and coverage.
(2) Surfactant L-77 can improve water penetration of hard to wet soils and provide more uniform distribution of applied moisture.
(3) Surfactant L-77 is generally compatible with pesticides and fertilizer solutions.
(4) Surfactant L-77 may cause excessive foam if not properly added to the spray tank. To minimize foam generation, add Surfactant 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 Surfactant L-77.
(5) Do not allow spray mixes containing Surfactant L-77 to sit over 36 hours.
