L/acre (minimum).
Mixing Instructions
Fill with water to
⅔
using continuous agitation; add Barricade SG, agitate for 5 minutes, then add tank mix partner. If
tank mix partner is an emulsifiable concentrate, reduce agitation to prevent invert emulsion. Complete filling tank and
spray.
Application Tips
Higher spray volumes needed with a dense crop canopy and/or large weeds. Weeds should be less than 10 cm tall
or across at application. Barricade left in the tank for more than 24 hours might have reduced effectiveness. When
crop is under stress, application may result in crop injury such as temporary crop colour lightening or a slight height
reduction. Clean sprayer immediately after application and use ammonia.
Note:
PERIMETER™ Herbicide activity is influenced by weather conditions. Optimum activity requires active crop
and weed growth. The temperature range for optimum activity is 12
°
C to 24
°
C. Reduced activity will occur when
temperatures are below 8
°
C or above 27
°
C. Frost before application (3 days) or shortly after (3 days) may reduce
weed control and crop tolerance. Weed control may be reduced during stress conditions, e.g. drought, heat or cold
stress, or if weeds have initiated flowering, or if heavy infestations exist.
