The U.S. Division of Agriculture has devoted $500,000 to appear at the path of hemp and switchgrass pollens. The purpose is to predict how and exactly where pollen grains travel.
“Having a validated and reputable extended-distance transport prediction model for wind-dispersed pollen is essential to establishing acceptable isolation distances” for crops like hemp, plant sciences professor David Schmale stated in a Virginia Tech statement announcing the grant.
Researchers say the function could aid inform laws about distance needs amongst hemp varieties that incorporate males and females – normally cultivars for fiber and grain production – and varieties of hemp and marijuana grown for flower production, exactly where female plants are kept away from males to steer clear of pollination.
The investigation will be carried out working with drones mounted with pollen sensors. The drones will gather air samples to locate out how and exactly where hemp pollen grains travel.
Virginia Tech’s investigation might also appear at how far specific herbicides and fungicides travel in the air, a concern for organic farmers worried about chemical drift.
