- DPR strawberry group releases fumigant replacement plan
- Action plan offers direction
- California agriculture is facing the loss of the fumigant methyl bromide.
Solutions: Short term, anaerobic soil disinfestation looks promising. Steam injection as well as solarization also works well. Long term, breeding for resistance to soilborne pests offers the ultimate solution.
Action plan offers direction
Leahy says the action plan offers direction to both short and long term solutions.
“Short term, anaerobic soil disinfestation looks pretty promising. Steam injection as well as solarization also works well,” said Leahy, who has farmed both in California and Nebraska. Long term, breeding for resistance to soilborne pests offers the ultimate solution.
“We need to start working with soil life. It is a key component of farming. Our ancestors understood that, and we need to go back to it,” he said.
The working group plan is the first to tackle the problem. Leahy said it is a continuation of what growers are already researching. “There is some promising work already being done, and we need to get it out so growers can try it on a larger scale. We need to have researchers and educators explain it to growers so they can make those changes,” he said.
Leahy has high praise for the strawberry industry. He called them “like the canary in the mine” who are willing to gamble heavily on finding solutions.
“I have been on farms doing some great research ... like Driscoll where they did a lot of research on cover corps only to find that they often compound the problem. That is the kind of research we need to do.
“There are a lot of innovative strawberry growers out there working with soils. It is pretty risky when you consider how much of an investment they have in crops. They are the true leaders in this effort,” he said.
The action plan complements DPR’s research partnership with the California Strawberry Commission. The focus of the $500,000, three-year research project announced in March is growing strawberries in peat or substances other than soil. It also complements DPR’s new research grant program, which includes $500,000 annually for grants that DPR would award for researching production practices that reduce reliance on fumigants and other high-risk pesticides.
The working group, research partnership and grant program are paid for out of the special fund generated by fees that support DPR’s programs. The group includes: Chair: Leahy.
