performance of ready mix formulation of fenoxaprop metribuzin for the control of grass and Broadleaf Weeds in wheat
Indian Journal of Weed science, 2011Co-Authors: U S Walia, Tarundeep Kaur, Shelly Nayyar, Rupinder KaurAbstract:An experiment was conducted for three years at the Research Farm of Department of Agronomy, Punjab Agricultural University, Ludhiana during rabi seasons of 2007–08 to 2009–10. The experimental field was heavily infested with Phalaris minor and Broadleaf Weeds. A new herbicide i. e. AEF 04 6360-8%+DIC 1468–14%-22% EC (fenoxaprop-P-ethyl+metribuzin) was applied at 165, 220, 275, 330 and 550 g/ha as post-emergence (30–35 DAS). The results of three years revealed that application of this herbicide at 275 and 330 g/ha provided effective control of P. minor and Broadleaf Weeds in wheat crop and were found statistically at par with Atlantis 3.6 WDG (mesosulfuron 3.0%+iodosulfuron 0.6% at 12+2.24 g) on dry matter accumulation by P. minor and Broadleaf Weeds. On an average of three years, post-emergence application of AEF 046360-8%+DIC 1468–14%-22% EC at 275 and 330 g/ha as well as Atlantis 3.6 WDG at 14.4 g/ha increased wheat grain yield by 58.8, 64.2 and 67.3% as compared to unweeded (control) treatment, respectively.

Studies on Composition of Weed Flora of Wheat (Triticum aestivum L.) in Relation to Different Tillage Practices under Rice-Wheat Cropping System
Indian Journal of Weed science, 2007Co-Authors: Amandeep Singh Brar, U S WaliaAbstract:A field survey was conducted during 2004–05 and 2005–06 in the three districts of Punjab i. e. Patiala, Sangrur and Moga with the objective to study the shift in weed flora of wheat (Triticum aestivum L.) in relation to different tillage practices. Thirteen weed species were found infesting wheat fields and of these, Phalaris minor, Polypogan monspeliensis, Poa annua, Rumex dentatus, Medicago denticulata, Anagallis arvensis, Lepidium sativa and Malva neglecta were most common. Grass Weeds had slightly higher relative density, relative frequency, importance values and summed dominance ratio under conventional tillage as compared to zero tillage, whereas these values of Broadleaf Weeds were slightly higher under zero tillage as compared to conventional tillage. Slightly higher population of grass Weeds was observed under conventional till than zero till sown wheat and the differences were found to be significant in Patiala district. Higher population of Broadleaf Weeds was observed under zero tillage as compared to conventional tillage technology and these differences were significant in Sangrur and Moga during first year and in Patiala and Sangrur during second year. Dry weight of grass Weeds was slightly higher in conventional tillage than zero tillage technology and differences were significant in Patiala and Sangrur during 2004–05 and in Moga district during 2005–06. However, dry weight of Broadleaf Weeds was significantly higher under zero tillage technology as compared to conventional tillage technology during both the years in all the districts.

Influence of Planting Techniques and Weed Control Treatments on Nutrient Uptake by P. minor Retz. and Broadleaf Weeds in Wheat (Triticum aestivum L.)
Indian Journal of Weed science, 2007Co-Authors: Amandeep Singh Brar, U S WaliaAbstract:Field study conducted at experimental farm of Punjab Agricultural University, Ludhiana (India) during rabi seasons of 2004–05 and 2005–06 revealed that nutrient uptake by Phalaris minor as well as Broadleaf Weeds were significantly reduced with zero till sowing in standing stubbles, zero till sowing after partial burning and bed planting techniques as dry matter accumulation by Weeds was significantly less in these treatments as compared to conventional tillage and zero tillage techniques (without stubbles). Post-emergence application of clodinafop 60 g/ha f. b. 2, 4-D 0.5 kg/ha, sulfosulfuron 25 g/ha and mesosulfuron+iodosulfuron 12.0 g/ha significantly reduced the dry matter accumulation by all Weeds and hence significantly reduced uptake of N, P and K by both P. minor and Broadleaf Weeds, whereas clodinafop 60 g/ha alone reduced dry weight and nutrient uptake of P. minor only as compared to control (unweeded) crop.

influence of Weeds within zea mays crop plantings on populations of adult diabrotica barberi and diabrotica virgifera virgifera
Agriculture Ecosystems & Environment, 1994Co-Authors: Daniel M Pavuk, Benjamin R. StinnerAbstract:The influence of Weeds in corn plantings on abundance of adult Diabrotica barberi Smith & Lawrence and Diabrotica virgifera virgifera Le Conte (Coleoptera: Chrysomelidae) was examined. Four treatments were established: corn without Weeds, corn principally with Broadleaf Weeds, corn principally with grassy Weeds, and corn with a mixture of Broadleaf and grassy Weeds. Significantly greater numbers of D. barberi adults were collected from corn in treatments with Broadleaf Weeds than from corn in treatments without Broadleaf Weeds for both years of the study. Relative abundance of adult D. barberi on corn was not significantly different between treatments containing grassy Weeds and treatments without grasses either year. Neither Broadleaf nor grassy Weeds significantly affected adult populations of D. virgifera virgifera either season; however, significantly more western corn rootworm beetles were collected from mixed Weeds than from Broadleaf or grassy Weeds in 1989. The presence of Broadleaf Weeds in corn plantings could result in greater numbers of D. barberi adults on corn plants, and possibly greater oviposition.
