My leylands are infested with bagworms. I bought Talstar and sprayed in late June early July.
It spit rain about 4 hrs after spraying and then poured about 2 days after. Should I retreat or wait a month or so?
Talstar P only needs an hour or two to dry, and once it is dry it does not matter if it rains 2 hours later or 2 weeks later, it should hold up the same once dry. So our answer is, you do not need to re-treat just yet. However, it would not, or should not anyways, hurt the tree if you wanted to apply a second application now that is not mixed as strong for good measure.
