Product Details

Zenivex E20 Mini Tote

Zenivex® E20 is 20% Etofenprox by weight. It is an oil-based formulation for use in Ultra Low Volume application. Although it doesn't require dilution, it can be diluted with oil. The low odor formulation can be used in hand, ground or aerial applications, requires no aquatic setbacks and is approved for use over crops in rural as well as urban settings. Zenivex® E20 has a very low toxicity profile for mammals and birds, and its dried residues are easy on bee populations. In addition, Zenivex® E20 can be sprayed over cropland. It does not contain Piperonyl Butoxide (PBO), and the oil-based formulation can be used both neat and diluted. *New York pending registration.

Additional Information



The most effective mosquito control programs use adulticides in conjunction with larvicides. This is especially necessary when there are an excessive number of adult mosquitoes in an area or the outbreak of disease poses a health threat to your community. Zenivex® E20 and Zenivex® E4 are oil-based formulations for use in Ultra Low Volume (ULV) applications and do not require dilution. Aqua Zenivex™ E20 has the efficacy and toxicity profile of Zenivex® products, in a water-dilutable formulation. All Zenviex® formulations are ready-to-use for hand, ground or aerial application, require no aquatic setbacks and have crop approval so you can spray throughout urban and rural settings.

Zenivex® mosquito adulticide gives you three alternatives for adult mosquito control. It is a high efficacy, reduced-risk adulticide that provides quick, permanent knockdown and reliable control of adult mosquito populations in any mosquito habitat.
