Insects thrive on GM 'pest-killing' crops
Jim Webster writes
Someone Any integrated pest management user knows that pesticides and beneficial insects are not very compatible. exactly, but your argument is as much in support of GM with its lesser pesticide use as it is against GM. Remember the alternative to GM is not organic but other conventional Actually pesticides are pretty useful for integrated pest management. If you can take out the incoming pest's first generation in the field then typically they will breed in the field margins, along with their predators. Sometimes that is enough to ensure a good population of predators entering the crop at the same time as the second generation of pests. Damage is thus reduced to the level you don't have to worry about it. That's typically why aphids in UK cereals only need autumn, or perhaps autumn+very-early-spring aphicides in most years (in practice pretty well every year). -- Oz This post is worth absolutely nothing and is probably fallacious. Note: soon (maybe already) only posts via despammed.com will be accepted. |
