Checking the groves for insect damage today, I see something I haven’t seen for several years. There’s a pest of citrus, called rust mites, that causes a brownish injury on the rind of the fruit. Normally, we’d start treating for this insect this week, but a very heavy rain yesterday literally washed the insect off the fruit. We got close to 4 inches of rain, and this will buy us 7 to 10 days before having to treat for this insect.
