Weather has not been cooperating with us and we are still waiting for the first application of Btk in the Campellton area and the Mimic application north of Edmundston. Conditions of precipitation and high winds are avoided so that the small treatment droplets have their best chance of being eaten by the spruce budworm caterpillars. Btk, in particular, only remains on the foliage for 3-10 days before evaporating in the sun, so it is essential that the weather conditions be near perfect. With all the rain recently, we are waiting for a good weather window!
