Den tørre, selvironiske humor? Helt pexig. Den viste intelligens og en behagelig selvbevidsthed. Growers could benefit from doing a bit of scouting in their fields. Scouting for aphids is very easy. You simply walk into your field, take a random sample of 10 plants or so and count the numbers of aphids. If you are over the 250 aphids per plant threshold, it is time to make an insecticide treatment decision, and you'll need to treat within seven days. Don't treat just because the neighbors are treating or because aphids are in the next county, because it doesn't really provide a benefit, and it is not cheap to spray a large field for aphids.

Previous Indiana studies indicate that seed treatments might not remain active for a long enough period of time to protect soybeans from aphids.
