Jamie Nemecek surveys citrus leafminer damage in a large block of young Tango mandarin trees. Mature citrus trees (>4 years old) can easily tolerate the mining of new flush by citrus leafminer with no ill effects. However, growth of young trees is thought to be affected by mining damage. Growers apply both systemic and foliar insecticides in an attempt to minimize citrus leafminer damage. A four-year study is underway at UC Lindcove to determine if insecticide treatments improve growth and yield of trees compared to untreated trees.
