Alternative ideas for dormant fruit tree spraying?
Over the last week I have sprayed around 150 dormant fruit trees with the lime-sulpher/dormant oil.
I gather it is certified organic approved, but I do NOT like the idea of oversprayed oil wafting all over the ground below trees.
Can I use canola oil, or any more biodegradable oil? Any ideas on emulsifiers?
Would like to hear any opinions on this. Thanks
