DIRECTIONS FOR USE
IMPORTANT: This information is approved as part of the Product Label. All instructions within this section must be read carefully in order to obtain safe and successful use of this product.
For the best results, apply Barclay Avoca before disease appears according to a planned programme on the expected incidence of disease or as soon as disease appears. Control becomes more difficult once disease is established and potential yield may be reduced. The recommendations must be supplemented when necessary to meet specific disease threats not controlled or not fully controlled by chlorothalonil.
 
WINTER AND SPRING WHEAT
Disease
Leaf spot
Glume blotch (Septoria spp.)
The spread of Septoria spp. on upper leaves and ear is often associated with mildew. Reduced efficacy of Barclay Avoca might result when high mildew levels also occur. Overall efficacy can be improved by tank-mixing with an approved mildewicide (see Compatibility).
Timing
Early disease appearance/high risk situations: spray if necessary after pseudostem erect to second node GS30-32 when disease first appears or if conditions appear favourable for disease development
Rate
2.0 l/ha in at least 200 l/ha water.
