[QUOTE="Brisel, post: 6328236, member: 166"] Good topic (y) I feel your pain. I hate trying to the right thing then get kicked in the teeth by pest numbers that the beneficials can't keep up with. CSFB was the first pest I had to spray for in over 5 years of beetle banks, field margins, nectar flower plots etc. Here's my version; Summer pests like aphids & pollen beetle are the ones we could tolerate the most. The beneficials will work hardest here. The same cannot be said for the autumn ones like CSFB and BYDV carrying aphids (Bird cherry and grain). CSFB ate my emerging osr crop right next to beetle banks that hadn't seen a spray since they were formed 7-10 years ago. IMO part of the problem here is the flying pests that land in your fields You don't get an anti virus without a virus. You don't get a predator without prey. All you can really do is create as much habitat for your predators and hope your prey breed up slowly enough that the predators can keep up. The first appearance of the pest is where the beneficials can have the greatest effect. I you're going to grow linseed, sow wild flowers that flower when your linseed emerges. Do the same for flowering plants in August so you have predators in your field margins when you sow your osr. You get the idea. If you do have to treat, manage your water. As [USER=819]@John Slejpner[/USER] rightly said, condition hard water so you get 100% of your insecticide not 50% with the rest locked up by dissolved cations in hard alkaline water. Use wetters and finer quality nozzles. You're hitting small targets so you need small droplets. You can't expect this to kill a small bug unless it smacks it directly on the head!
