Influence of Adjuvant Arkopal with Panther weeds control, wheat yield, Photosynthetic Pigments and Anatomical Features of Wheat Leaf.
Abstract: Two field experiments were conducted at the Experimental Station of Agricultural Research Center, El-Serw Station, Damietta Governorate Egypt, in 2008/2009 and 2009/2010 winter seasons to determine the effect of adjuvant Arkopal N100 on the efficacy of Panther (Isoproturon + diflufenican) at the rates of 450, 510 and 600 cm3/fed with or without adjuvant Arkopal N100 at the rates of 4, 8 and 12% as well as hand pulling twice and weedy check on weeds and wheat plants. Results illustrated that all weeded treatments decreased dry weight of each weed group compared with unweeded check. Panther at the rate of 600 cm3/fed tank-mixed with adjuvant of Arkopal N100 of 4% concentration came in the first order for decreasing number, fresh and dry weight of total weeds. Panther at the rate of 600 cm3/fed tank-mixed with adjuvant Arkopal N100 at 8% came in the second rank followed by that of Panther at the rate of 510 m3/fed tank-mixed with adjuvant Arkopal N100 at the rate of 8%, Panther at the rate of 510 m3/fed tank-mixed with adjuvant Arkopal N100 at 4% and hand weeding-twice at 30 and 45 days after sowing. Also, the previous treatments gave the highest values of chlorophyll b, a+b, carotenoids, yield and yield components of wheat as well as N, P and K percentage in straw wheat. While, Panther at the rate of 600 cm3/fed tank-mixed with adjuvant Arkopal N100 8% produced the maximum values of chlorophyll a. Mixing Panther at the rate of 600 cm3/fed with adjuvant Arkopal N100 at 4% exceeded the rest of other weeded practices for enhancing leaf thickness in the keel region, mesophyll tissue thickness, large vascular bundles dimensions (length and width), xylem tissue thickness and meta xylem vessel diameter. Thus, the use of adjuvant at 4% can play a good role in enhancing Panther efficacy either at full reduced rates of Panther for weed control in wheat
