Hola Juanse It sounds like you are saying that they are going to do a foliar application. At what rate are they going to apply (how much active ingredient per litre, how many litres per hectare? I would be interested to know how the application rate varies between foliar application and application in the drip irrigation system. (Chemigation in pumpkins is problematic according to others on this list; I wonder whether that is because of the application rate, or because the application is less controllable). From my own experience: once they quit doing foliar applications and soil injection of imidacloprid and started treating the seed set only (at a greatly reduced a.i. per hectare) the problems I saw went away for the most part. If the blueberry fields you are referring to are the home fields around your base in Gorbea, then you should have them spray around the corner of the farm where you store your your equipment when it is dead calm because at this time of the year I expect you have all your supers stored in that area. I would be most concerned about the weeds which may be sprayed in a foliar application. Is there anything flowering at this time of the year? I seem to recall that the blueberry rows are extremely clean of weeds, but anything that is flowering could be a real problem.
