Often seen as the big challenge to food production, this seminar will explore some of the positive as well as negative aspects of WP&D. You will learn about the “systems approach” to developing in-built resistance to many common problems and see how it is even possible to get weeds on your side at times! We will explore how WP&D become established, how they impact on crops and how you are going to maintain a degree of control over their negative effects.
After lunch there will be a tour of the fields and walled garden crops to see how weeds, pests and diseases are notably absent most of the time and how systems have been developed to ensure a healthy and productive farm.
The seminar is a participative workshop so you get to join in, share your ideas and questions with the whole group and you may be put into a working group as part of the day’s activities. At the end of the day you will go home with a much clearer idea of the role of WP&D on the farm
Seminar length is 6 hours including lunch.
