Tom Dykstra and I discussed the concepts of plant health, nutrition management, and insect resistance in a rapid fire, intense one hour webinar, with a specific emphasis on controlling aphids in sugar beets and flea beetles in canola.
While the conversation was fairly high level, and didn’t get into the nuts and bolts of implementation, Tom’s knowledge of insect metabolism and the type of food sources they require to survive is unparalleled.
If you want to learn how to grow insect resistant crops, this webinar is a must listen. You kind find the recording on KindHarvest.ag here.
Tom uses a refractometer as a research tool, and describes a brix index of plant susceptibility to to different groups of insects at different brix levels. There is a big difference between using using brix as a research tool and using it as a crop management tool. You can read my thoughts on using brix here.
