SumiShield 50WG

SumiShield™ 50WG is an Indoor Residual Spray (IRS) containing a new mode of action active ingredient. With resistance to pyrethroids so widespread in Africa, Sumitomo Chemical deliberately chose a single ingredient Non-Pyrethroid formulation so that true insecticide rotational strategies could be employed. SumiShield 50WG provides excellent control of malaria transmitting mosquitoes benefiting from a non-repellent formulation, low toxicity, ease of use and transportation

The Need For A New Mode Of Action Ingredient For IRS

Managing resistance to insecticides is one of the major issues facing the global fight against malaria. Resistance to at least one insecticide has been identified in over 75% of countries with on-going malaria transmission. The effectiveness of IRS is under threat due to the spread of pyrethroid resistance and the difficulty many countries find in rotating the class of insecticides they use year upon year, largely due to a lack of choice.

Product Information

SumiShield 50WG is based on the neonicotinoid insecticide clothianidin. This is the first new MOA chemistry to be introduced to the vector control market in over 40 years. Following positive independent laboratory and field trials, SumiShield 50WG is the first vector control product listed by WHO under the new Prequalification (PQ) system.

Extensive data already exists of the environmental and toxicological impact of clothianidin. SumiShield 50WG is odourless and trials show it has a low toxicity through skin contact and inhalation and is practically non-toxic to bird and aquatic life.

How It Works

SumiShield 50WG has been purposely designed as a single ingredient formulation Non-Pyrethroid and as such, it is Non-repellent. It means that mosquitoes are exposed to the active ingredient for longer than with some other insecticides, such as pyrethroids and DDT. Therefore, mosquitoes are more likely to die from link exposure as they can intake relatively large amounts of insecticide while resting on treated substrates. This increases effectiveness and reduces the opportunity for resistance to develop.

How To Use SumiShield 50WG

SumiShield 50WG can be sprayed to the inside of houses and residences on walls and other surfaces that serve as a resting place for mosquitoes. Delivered in small, easy to handle sachets, the product readily dissolves in water, with only one sachet required per tank, making transport simple and cost effective
