Polyether-modified heptamethyltrisiloxane-polyether-modified silicone oil

 

Specification

XJY-207 Polyether-modified heptamethyltrisiloxane-polyether-modified silicone oil is a commonly used silicone surfactant and is widely used in agriculture to improve the surface diffusion effect of pesticides, improve the diffusion performance, and thereby improve the effectiveness of drugs.

 

Advantage

1. Super properties of wetness and expansion

2. Stomatal penetration rate

3. Improve the prevention effect of pesticides

4. Reduce the spray volume,

5. No harm to human

 

Application

 

XJY-207 Polyalkyleneoxide modified Heptamethyltrisiloxane is a modified trisiloxane silicone surfactant with a special structure. It has super properties of wetness and expansion as well as stomatal penetration rate. It can improve the prevention effect of pesticides and reduce the spray volume, widely used in the fields of pesticides herbicides, insecticides, acaricides, fungicides, plant growth regulating agents, and other aspects. XJY-207 has physical inertia, no harm to human beings or the environment.

 

XJY-207 Polyether modified silicone, Polyalkyleneoxide Modified Heptamethyltrisiloxane is an agricultural super-spreading agent, which can be added to pesticide formulations or tank-mixed sprays. At 0.1% concentration (WT), the surface tension of water can be reduced by 20.5mN/m. After mixing with the pesticide solution in a certain proportion, the contact angle between the spray liquid and the leaves can be reduced, thereby increasing the coverage of the spray, and XJY-207 Polyalkyleneoxide Modified Heptamethyltrisiloxane spreading agent can absorb the pesticides through the stomata of the leaves, which is helpful for improving the efficacy and reducing the pesticides. It is very effective to reduce the number of pesticides, save costs, and reduce environmental pollution caused by pesticides.

 

XJY-207 Polyalkyleneoxide Modified Heptamethyltrisiloxane can enhance the performance of agricultural chemicals, especially fungicides, insecticides, water-soluble broad-leaved herbicides, and plant growth regulators.

 

Packaging

 

50kg pails and 200kg drums, Any special requirement may be negotiated with us.

 

Storage

 

XJY-207 Polyalkyleneoxide modified Heptamethyltrisiloxane is non-dangerous goods, stored in the dry and cool environment.

 

Provecta - A Physical Action Adjuvant from ICB Pharma

2016年9月23日

Adjuvants play significant role in reducing several problems encountered during spray application. Problems encountered during pesticide application include: drift, coverage, adherence, volatilization, penetration, solubility, surface tension, foaming, suspension, evaporation, stability, incompatibility, alkalinity degradation and odor. Adjuvants are formulated to  minimize these application problems by buffering, sticking; also by reducing a factors like foam, spreading, evaporation, emulsifying, drift, volatilization, and odor. Adjuvants also help highlight where spray has been applied, increasing compatibility, dispersing, and wetting.

 

This article discusses a totally new adjuvant that enhances the efficacy of the formulation through physical mechanism, which is a completely new and promising approach to the current problems in  the pest control industry. The product “Provecta” is a unique mixture of polymeric compounds  to be combined in the spray tank with insecticides (toxicants) for more effective treatment. It generates specific contact action resulting in dehydration and eventual suffocation through the following mechanisms:

 

Spreading

 

When applied it provides quick and even spreading, helping penetration precisely in the treated surface. It also increases the likelihood that the toxicant is transferred to the insect by contact, enhancing the bioavailability of the active ingredient. This is a crucial parameter when dealing with resistant pest populations harboring in inaccessible locations, e.g  bed bugs.

 

Immobilization

 

After application it creates a cross-linked 3-Dimensional network structure on the treated surface, tightly covering all developmental stages of the pest insects and immobilizing them. This leads to increased exposure to the toxicant. It also improves the efficacy through additive effects of the two mechanisms, namely neurotoxic and physical.  

 

Dehydration and/or suffocation

 

Once applied the formulation completely penetrates the body surface of pest and fills their spiracles (which have hair at the opening for filtering and a valve for controlling air flow) either preventing them from closing or keeping them closed. This leads to dehydration and suffocation. Both the physical effects eventually kills the insect pest.

 

Provecta, an effective adjuvant with physical action against pests may deal with expanding problem of resistance to insecticides. It also has a number for favorable features such as:

 

·       High efficacy in controlling numerous pest species.

·       The physical mode of action eliminates the possibility that pests will become resistant to this specific treatment.·      

Synergetic effect results in reduced rate of insecticide or dosages.

·       Perfect at locations where pesticide application predominates, resulting in development of resistance.

·       Recommended to be used in tank mix to control resistant populations in not easily accessible locations i. e. bed bugs.

·       Equivalent to the effects of two different mechanisms added together (neurotoxic and physical).
