We are well into spring and crops being cased now will be cropping in May and June - so growers need to think about their fly control measures now. The best way to prevent flies moving from house to house is to treat all houses when the populations start to increase - Springtime! And since good fly control is a vital element in controlling potential fungal disease, those farms that drag their feet with control measures could face more problems at a later stage. Nemasys M is a natural fly control agent which is the most effective and the most popular product of its type on the market in the UK and Ireland. Being a natural product there are many advantages over conventional chemical products including competitive pricing.
