    Alternative Strategy: Application Rate Reduction. Timberlands Limited have trialled different rates on the many weed species and infestation levels. This has allowed Timberlands Limited to best select the herbicide and rates for the control required. In most cases this has lead to an active ingredient rate being applied lower than recommended by the pesticide manufacturer and label detail. It should be noted that the rate of Terbuthylazine has reduced from around 20l/ha to between 12 and 15 l/ha over the past 15 years. These trials are continuing in conjunction with the flow metering and Callisto trials.
