Product Information
Sumilarv 2MR
SumiLarv™ 2MR is a polymer matrix release formulation presented as a 5.5 cm diameter
plastic disc weighing 2 g containing 2% w/w pyriproxyfen. SumiLarv 2MR prevents mosquito
pupae from developing into flying adult mosquitoes which can later bite humans. SumiLarv
2MR has been developed by Sumitomo Chemical Co., Ltd.

How To Use
SumiLarv 2MR should be placed in water containers at a rate of one disc per 40-500 liters of
water, depending on local registration. The disc will sink to the bottom of the container and the
active ingredient pyriproxyfen will be released slowly from the matrix of the disc to give a long
duration of efficacy. As water is used and replaced the disc will release more pyriproxyfen to
maintain an effective level to control the mosquitoes. If containers are emptied and cleaned then
place the disc in the shade and put back in the container after refilling with water.
