[QUOTE="Lowland1, post: 6328536, member: 66524"] We are growing vegetables and as such are scouting the crops regularly. We have found that in most cases your pest numbers will rise up to a point when you are just about ready to spray when all of a sudden they dip as the beneficials start to work. The problem is holding your nerve long enough for this to happen. If you are too quick to spray you will wipe out the good insects but there are so many other factors to consider such as what stress the crop is under. In good growing conditions the crop will grow away from any insect pressure but if under stress the insects will cause a lot of damage. My Dads rape was destroyed this year mainly because I don't think it was drilled well and as such could not get away from the beetles. We have made an effort to avoid knockdown sprays and use target specific chemicals but when your supermarket customers are shouting about aphids there is a lot pressure to use a rapid knockdown chemical which I think in the long term is counterproductive. We are learning a lot about insect life cycles and likes and dislikes but you have to have joined up thinking whatever you do will be useless if your neighbour allows things to get out control as these things are very mobile.
