| Popis: | The effect of butachlar, oxadaiason, pendimethalin, avirosan, bentazon and their combinations for control of barnyard grass and umbrella sedge in rice (Oryza sativa L.) was studied in two field experiments at the Experimental Farm of the National Research Centre at Shalakan, Kalubia Governorate; Egypt, during 1982 and 1983. The differences in response among weeds and rice to post‐emergence herbicides and their combinations were very variable. The combination herbicides: pendimethalin at 0.83 kg + bentazon at 1.44 kg/feddan∗ butachlor at 1.0 kg + pendimethalin at 0.83 kg/feddan, oxadiaton at 0.5 kg + pendimethalin at 0.83 kg/feddan and avirosan at 0.5 kg + bentazon at 1.44 kg were very effective against Echinochloa crus‐galli. Oxadiazon at 0.5 kg and avirosan at 0.5 kg as well as the combination of Butachlor at 1.0 kg + oxadiazon at 0.5 kg or Avirosan at 0.5 kg and avirosan at 0.5 kg + bentazon at 1.44 kg/ feddan gave the best weed control against Cyperus difformis. All combination herbicides as w... |
