Vine Weevil ProblemAnswered by Lynn Posted in Category Pest Control & Nature
I treated my containers with Provado vine weevil killer earlier in the year. Can I now use the nematodes or will the previous application stop them working?
Provado keeps working in the soil for 4-6 weeks so as long as you applied it more than 6 weeks ago you are perfectly safe to apply the Nematodes. Nemasys Vine Weevil Killer is suitable for Autumn application so now is a good time whilst the soil is still in excess of 5 deg C.
Adult weevils can also be searched for by torch light and removed from plants if you feel the urge to do so!!
Hope you get the problem sorted.
