性能描述 技术资料
Silwet L-77 is a chemical mixture of polyalkyleneoxide modified heptamethyltrisiloxane (84%) and allyloxypolyethyleneglycol methyl ether (16%). It is an essential infiltration media ingredient for all Agrobacterium-based transformations of Arabidopsis and other plants.10 mL and 35 mL are sufficient quantity to prepare 33 L and 115 L of vacuum infiltration medium when used at the recommended rate of 0.03%, v/v, respectively.


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 36

hours.
