There are numerous regulations at municipal, provincial and federal levels that govern access to water as well as the implications associated with run-off water. Growers have responded by constructing elaborate pond and water recycling systems but are now challenged to maintain the quality of water in their pond systems required to keep their modern irrigation systems operable. In this webinar Dr. Jeanine West will share water quality management strategies based on her expertise and preliminary research findings. Time will be allocated for Q&A.

OMAFRA Lunch and Learn Series has Answers.

REPOSTED FROM: SARAH JANDRICIC, GREENHOUSE FLORICULTURE IPM SPECIALIST, OMAFRA
