Shu Dan is a premix of Bt and Avermectin,
which is highly effective to lepidopteran insects and acarids with
effect methods of contact and stomach-toxic. As a result, the
insects can not move and take food till death. Shu Dan is mainly
used for developing non-pollution vegetable base of suburb of big
and middle cities. This biopesticide has special activities
against pests resistance and cross-resistance to other pesticides
and is easily decomposable, no residue, prolonged efficiency,
safety.

larvae. Re-apply each 7 days or as necessary under a pest
management progamme that includes frequent scouting. If rapid
knockdown of heavy larvae population is necessary, include an
effective contact chemical insecticide in combination with Shu
Dan. During periods of high temperatures, larvae will progress
through early instars very rapidly and early application timing is
necessary for control.
