ANSWER: In the 1980s through the mid-1990s, the three major drivers of change in corn and soybean weed management were:
1. The herbicide-biotechnology-seed industry.
2. Farmers looking for simpler, more effective solutions to tough weed control challenges.
3. University weed management scientists and extension specialists.
In the decade ahead, the three major drivers of change in corn and soybean weed management are likely to be:
1. Consumers and citizens worried about the collateral damage stemming from more intensive herbicide use.
2. Food companies, through supply-chain interventions.
3. Farmers choosing to reduce reliance on herbicides by adoption of multi-tactic, “many little hammer” weed management systems.
