Study of Effective Promotional Tools for Enhancing the Use of Pre- Emergence Herbicide in Paddy Crop

Abstract

The article on title “Study of effective Promotional Tools for enhancing the use of Pre-Emergence Herbicide in Paddy Crop” was carried out under the guidance of Dr. NITIN BARKER. Paddy (Oryza sativa) is the major staple food for a large population of world’s population especially in South and East Asia, 65% of the India’s population major staple food is rice. Rice is an important source of food worldwide. However, the growth of weeds in paddy fields pose a major biological threat to higher rice productivity and quality. Weeds have many variable characteristics compared to the crop for examples lack of seed dormancy, uniform growth and high yields. Thus, weeds tend to show larger potential capacity to adapt to stress (e.g., climate change) than crop plants. Consequently, effective management of weed is a vital pre-requisite notable production of rice. For instance, if crop losses of approximately 10–20 % are recovered through effective weed management with the use of appropriate herbicides, there will be additional yield of 0.3–0.6 t/ha. Different weed management practices were studied in paddy in present study were bensulfuron methyl 60 g + 600 g a.i ha-1 as pre emergence followed by mechanical weeding at 30 DAS/T, bispyribac sodium @ 25 g a.i ha-1, farmer’s practice and weedy check. among weed management practices, pre emergence application of bensulfuron methyl + pretilachlor mixture followed by mechanical weeding at 30 DAS/T resulted in higher B:C ratio compared to other methods of weed control. Finally, it could be concluded that there are good opportunities for Herbicide (Stilleto) to create a market space in the study area. The company need to focus on certain factors like farmer’s expectations, field demonstrations and creating awareness in the study area.
