As take-all is a soil-borne fungus the most effective chemical control comes from a seed treatment. Currently the only specialist take-all seed treatment available is Latitude which should be used where ever a risk of take-all has been identified:
- Second and third wheat
-
Winter barley, Triticale or spring wheat following a cereal
-
First wheat after, non-cropped land or a spring cereal or even after breakcrops which followed overwintered stubbles with cereal volunteers or grass weeds
Recent seasons have favoured take-all, as have trends towards earlier drilling of subsequent cereals and tighter cereal crop rotations.
Yield and quality
Latitude has recovered half to two-thirds of the yield lost to take-all in second and third wheats in more than 800 UK and European trials over the last seven years. It is likely to be cost-effective wherever take-all is a problem.

In UK trials over the past 10 years Latitude has always delivered a return over and above the cost of the seed treatment

Use of Latitude can allow drilling up to 14 days earlier, assuming all other things are equal
