application can be made 7 - 14 days later. Use higher rate
and shorter interval when disease pressure is high.

chickpea, lentil,
field, navy, pinto
bean, field pea)

Ascochyta
spp
.)
400 - 600
mL

continue on a 7 - 14 day interval. Use higher rate and
shorter interval when disease pressure is high.
Grey mould (

500 - 600
mL
Suppression of Asian soybean
