Technical Annual Report 2000/01 161 Dormex Research Project 2000: Research was conducted in 2000 to further assess the effectiveness of a number of the treatments used in the previous season. Treatments varied between cultivars and consisted of the following: Flame Seedless - Dormex 5% + Agral 0.1% (D5% A 0.1%), Dormex 5% + Chemwet 0.1% (D5% C 0.1%), Dormex 2% + Chemwet 3% (D3% C3%.), Dormex 12% + Chemwet 0.1% (D12% C 0.1%). Menindee Seedless - Dormex 5% + Agral 0.1% (D5% A 0.1%), Dormex 4% + Chemwet 0.5% (D4% C0.5%), Dormex 2% + Chemwet 3% (D2% C3%) and Dormex 12% + Chemwet 0.1% (D12% C 0.1%). Thompson Seedless - Dormex 5% + Agral 0.1% (D5% A 0.1%), Dormex 4% + Chemwet 0.1% (D4% C0.1%), Dormex 2% + Chemwet 3% (D2% C3%). Note that Dormex 12% + Chemwet 0.1% was applied to Flame Seedless and Menindee Seedless. This was the result of an incorrect spray mix. The results are included to demonstrate that higher rates of Dormex do not increase the rate of budburst. Method: The trials were conducted in three commercial table grape plantings on the Territory Grapes property. The plantings comprised Vitis vinifera cultivars Flame Seedless on own roots, Menindee Seedless on Sultana H5 and Thompson Seedless on own roots. Ten two-bud spurs on Flame Seedless vines were tagged. The varieties Menindee Seedless and Thompson Seedless were cane-pruned. A total of 20 buds were tagged on the eight canes on vines of these varieties. Treatments were applied from 4 to 6 July 2000, using the accepted commercial method, using a boom mounted on a 3,000 litre trailed spray unit. The marked buds on the spurs and canes of the treated vines were assessed twice each week beginning on 2/8/2000. The effectiveness of each treatment was assessed by comparing the number of days it took for buds, which had been tagged to reach 80% bud burst. Results: Flame Seedless When assessments began on 2/8/2000 all treatments except Dormex 12% Chemwet 0.1% had reached more than 45% bud burst with D5% A 0.1% at 52%, D2% C3% at 49% and D5% C 0.1% at 47% budburst. On 19/8/2000 D5% A 0.1% had reached 94% bud burst, D5% C 0.1% had reached 87% bud burst and D2% C3% had reached 84% bud burst. On 25/8/2000 D5% A 0.1% had reached 99% bud burst, D5% C 0.1% had reached 93% bud burst and D2% C3% had reached 87% bud burst (Figure 1).
