LinkedInBroad Mite Trial
We have had resurgence of broad mite damage on coastal lemons this year. We haven't seen damage like this in a long time. Chlorpyriphos should care of it, but with small orchards, spray drift can be an issue. We looked at releasing the predatoiry mite Neoseiulus californicus. In the lab we challenged broad mite successfully so we took it out to the field. This is not the best time to release, because of the cold weather. Also it's best to release into a rising pest pressure. When there are too many pest mites, it's difficult to get good control. We released at an economic level of about 100 per tree, whihch would cost about $150 per acre. We've counted for 5 weeks and there is little apparent control in the field. ikt's just been too cold to build the population of beneficials. We'll try again next spring if the broad miter is there.
