<p>A synergistic herbicidal composition containing (a) penoxsulam and (b) pendimethalin provides improved pre-emergence to early post- emergence herbicidal weed control of undesirable vegetation in multiple crops, including rice, cereal and grain crops, turf, IVM, sugar cane and tree and vine orchards. The active ingredient ratio (weight-to-weight) of pendimethalin to penoxsulam at which the herticidal effect is synergistic lies within the range of between about 5:1 and 320:1, and in certain embodiments, a ratio of about 55:1. The rate at which the synergistic composition is applied will depend upon the particular type of weed to be controlled, the degree of control required, and the timing and method of application. The composition of the invention can be applied at an application rate of between about 160 grams active ingredient per hectare 30 (gai/ha) and about 1850 gai/ha based on the total amount of active ingredients in the composition.</p> |
