Gardening with Lynda Hallinan

Lynda tell us about a pest that is worrying those who grow tomatoes and potatoes. It's called the tomato/potato psyllid or TPP (Bactericera cockerelli) and it can completely undermine attempts to grow both crops. It was first found in NZ in 2009 and has got progressively worse since, leading to total crop failures, poor quality or low yields, and sick plants.
