Herbicide tolerant pulses at Keith

To identify the level of tolerance of PBA Hallmark XT lentil to sulfonylurea herbicides (SU) applied as simulated low-level residuals from a previous cereal crop and imazethapyr when applied post emergence (4-5 node growth stage).To identify the level of tolerance of PBA Bendoc faba bean to sulfonylurea herbicides (SU) applied as simulated low-level residuals from a previous cereal crop and imazamox + imazapyr when applied post emergence (4-5 node growth stage).本研究旨在测定PBA Hallmark XT小扁豆（PBA Hallmark XT lentil）的耐受水平，其受试药剂包括两类：一类为以模拟前茬谷类作物残留形式施加的磺酰脲类除草剂（sulfonylurea herbicides, SU），另一类为苗后（4-5节生育期）施用的咪唑乙烟酸（imazethapyr）。同时，本研究还将测定PBA Bendoc蚕豆（PBA Bendoc faba bean）的耐受水平，其受试药剂同样包括两类：一类为以模拟前茬谷类作物残留形式施加的磺酰脲类除草剂（SU），另一类为苗后（4-5节生育期）施用的甲氧咪草烟与咪唑烟酸混剂（imazamox + imazapyr）。
