Abstract:

A field experiment was conducted at regional research station of Bidhan Chandra Krishi Viswavidyalaya, Chakdaha, Nadia, West Bengal during Rabi season, 2012-13 to find out the various effect for controlling weeds in Rabi wheat (PBW- 343) grown with recommended package of practices by the application of 2,4-D Dimethylamine 50% SL. The experiment was laid out in Randomized Block Design, comprising of nine treatments. Treatments were as follows:T1 - 2,4-D amine 50% SL (Nufarm) @ 0.25 kg a.i. ha-1, T2 - 2,4-D amine 50% SL (Nufarm) @ 0.50 kg a.i. ha-1, T3 - 2,4-D amine 50% SL (Nufarm) @ 0.75 kg a.i. ha-1, T4 - 2,4-D amine 50% SL (Nufarm) @ 1.00 kg a.i. ha-1, T5 - 2,4-D amine 58% SL (Commercial) @ 0.50 kg a.i. ha-1, T6 - Metsulfuron methyl 20% WP @ 0.004 kg a.i. ha-1, T7 - Hand Weeding at 20 DAS & 40 DAS, T8 – Unweeded control treatments and T9 - 2,4-D amine 50% SL (Nufarm) @ 2.00 kg a.i. ha-1 and replicated thrice. In between aforesaid treatments, T9 - 2,4-D amine 50% SL (Nufarm) @ 2.00 kg a.i. ha-1 was included only for phytotoxicity observation. Phalaris minor, Cynodon dactylon, Avena fatua, Chenopodium album, Cirsium arvense, Fumaria parviflora, Anagallis arvensis, Cyperus rotundus and Cyperus iria were the dominant weed species. Among the weed control methods 2,4-D amine 50% SL (Nufarm) @ 1.0 kg a.i. ha-1(T4)(40.00, 16.73 and 34.34 % respectively) and 2,4-D amine 50% SL(Nufarm) @ 0.75 kg a.i. ha-1(T3) (40.00, 15.82 and 32.06% respectively) recorded the higher weed control efficiency after hand weeding twice at 20, 40 and 60 DAS. Among the herbicide treatments, maximum grain yield and lowest weed index were recorded under 2,4-D amine 50% SL (Nufarm) @ 1.00 kg a.i. ha-1 (T4) (1.80 t ha-1and 2.70% respectively) plot. The herbicide 2,4-D amine 50% SL tested at different doses and the tested new formulation is safe to the wheat crop.
