Summary
True potato seed production may contribute to the spread of several diseases and pests. MCPA (500 or 750 g a.i. ha−1) applied at early or full bud stage reduced berry number and seed number per berry, resulting in reduced true seed production. Effects on berry set differed between cultivars and were dependent on crop growth stage at application and true seed production was reduced most strongly in all cultivars with application at full bud stage. MCPA also slightly reduced yield and tuber size, but did not affect tuber dry matter content or fry colour.
