| Imazapyr has been used to control stump sprouting in stand of Eucalyptus plantations, where herbicide is applied to the tree trunk before cutting. The herbicide is applied exclusively on the stump to be killed, but little is known about the final fate of the molecule. Imazapyr exudation via roots of eucalypt grown in soil as the substrate was evaluated under greenhouse conditions. Different herbicide doses (0.000, 0.375, 0.750, 1.125, 1.500, and 3.000 kg ha-1 a.i.) were applied on the aerial parts of 8-month-old Eucalyptus grandis clonal seedlings, cultivated in pots with 18.0 dm³ of soil. Forty days after this treatment, the eucalypt plants were cut and a lateral opening in the containers was made and the plants inclined 90º, with plants sensitive to... |

| The objective of this study was to determine the effects of moisture content and blade cutting speed on the chopping and size distribution of sugarcane leaves. The experiments were conducted using 4 different moisture content percentages of 19.74, 30.97, 44.52 and 50.12 % w.b. and at the blade cutting speeds of 380, 630 and 880 rpm. The results revealed that moisture content and blade cutting speed significantly affected working capacity, weight and geometric mean particle length of the sugarcane leaves, and the results were statistically significant with confidence levels of 95%. The interaction of the two factors had a significant effect on the working capacity but did not affect the percent weight and geometric mean particle length of the sugarcane... |
