GENERAL INSTRUCTIONS

Stress conditions

Moisture stress is a particular problem, whether caused by drought or short term stresses, resulting from a combination of high temperatures and low humidity or by prior use of pre-emergence herbicides resulting in stunted root growth of weeds. An irrigation or effective rainfall must occur immediately before or after spraying if these conditions exist. Other stress conditions to avoid include use of pre-emergence herbicides resulting in stunted root growth of weeds, frost, waterlogging and extended cold conditions. Do not spray if any stress conditions are evident just prior to application.

Mixing

Add the required amount of ROXSTAR 250 WG (see table) directly to the spray tank which should be 50% full with clean water. After the product is fully dispersed complete filling the tank. The agitation system should be running during mixing and spraying. If agitation ceases and settling occurs, resuspend contents thoroughly before spraying. Ensure that all in-line strainer and nozzle screens in the sprayer are 100 mesh or coarser. Add any other product next. An oil adjuvant is essential and should be added last to the spray tank at 1 L/100 L of water recommended adjuvant for ground application and for aerial application use oil adjuvant at a rate of 1 L/ha. Oil adjuvant must be added to at least 10 times its volume of water especially where a suction (filling) probe is used.

Application

Time of application: ROXSTAR 250 WG is rainfast within 30 minutes. Do not apply ROXSTAR 250 WG if rain is expected within 30 minutes. To obtain the maximum benefits of this product, weeds should be sprayed when young and actively growing. Use the lower rates for grasses with up to 4 leaves. Use the higher rates for weeds with up to 3 tillers. Unless otherwise specified in the Critical Comments application may be made at any stage of crop growth but allowing sufficient time for the prescribed withholding period.

Method of application: Good spray coverage is essential for maximum results. Spray equipment must be checked and calibrated accurately prior to application.

• Boom spraying: Check height of boom above the target weeds to ensure the spray is evenly distributed and a double overlap pattern is obtained. An even distribution of droplets with a Fine spray quality is desirable for maximum efficacy. The inclusion of Supercharge coarsens the spray quality when applied through a TeeJet XR11002 nozzle such that a Medium spray quality results which will help reduce the likelihood of drift.

• Broadacre use: Water volumes per hectare will depend on nozzle selection and ground speed but should be in the range of 50-100 L/ha. 110° flat fan nozzles are preferred for use with this product. Use higher volumes of spray to achieve better coverage of dense, vigorous weed infestations and/or if the nozzles used produce coarser than a Fine spray quality (measured with water). The use of air induction nozzles is not recommended until further trial data is available.

• Aerial application: The product may be applied through boom or Micronair units in 20-30 L of water per hectare. The use of the higher volume is preferred due to more reliable results. Spray quality should be Fine and swath width should not be wider than recommended for type of plane and application unit. Weed control following aerial application may not be as good as from ground application.
