I am getting a lot of trees with pine scale. When is the optimum time to treat them?
The best time to treat is once in mid-April and then about 10 days later so that you get the crawlers when they hatch, which can occur over 2-4 week period. Once you've knocked the population back, you shouldn't have to retreat it every year. It may take two years, though, to get it under control.The length Safari 20SG will treat all depends on how large the diameter of the trees are. Please refer to the application charts on the product label.
