GE Silwet L-77 E表面活性剂 Silwet 77
Kinetic是一种*的非离子有机硅润湿剂/展着剂/渗透剂,用来加快农药吸收附着和营养物质渗透进植物的叶径。因其*的功能,比普通的表面活性剂使用的比率低很多。主要的有效成分为Silwet
L-77,在技术上避免了SilwetL-77在使用上的很多缺点,如农药有效成分的流失,对植物蒸发作用的影响,泡沫太多,在某些PH值条件下易水解,毒性太强等缺点。

Ø 树: 0.1%-0.2%v/v
详细介绍:
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.
