Prioritise seed treatment to protect against Rhizoctonia

Growers are being advised to prioritise seed treatments this season to protect against the risk of Rhizoctonia solani – the causal agent of black scurf and stem canker.

Growers are being advised to prioritise seed treatments this season to protect against the risk of Rhizoctonia solani – the causal agent of black scurf and stem canker.


Morley Benson explains; “Following reports of short dormancy break periods, due to the warmer, brighter conditions witnessed this growing season, we are advising growers to consider an early application of Rhino liquid (flutolanil), which should be applied to seed pre-dormancy break.


“The benefit of an early application is that it minimises any physical damage to the eyes during treatment and allows the seed to acclimatise to the product, meaning chits develop as expected.”


Rhino liquid can be used on seed potatoes grown for seed, ware or processing and uniquely offers preventative, as well as, curative and systemic activity. Rhizoctonia solani can cause substantial losses and uneven crop sizing. Impacting crops across the board, from seed and pre pack through to processing, it presents a serious threat to crop establishment.


Morley also reminds growers that for the best results, crops should be as free of soil as possible and dry before treatment commences, in order to prevent subsequent problems.
