“…Hence, the observed enhancements in grain, straw, and biological yield of rice can be attributed to the cumulative improvements in growth and yield attributes across the entire crop growth cycle. These findings align with those reported by Saranraj et al (2018) [5] , Khaliq et al (2012) [3] , Nazir et al…”

The field experiment was conducted during kharif, 2022 to evaluate the effect of different post emergence herbicides on growth and yield of rice (Oryza sativa L.) at Agronomy Farm, College of Agriculture, Dapoli, District Ratnagiri (M.S.). The experiment was laid out in a randomized block design with ten treatments which were replicated three times viz., (T1) Pyribenzoxim 3% + Penoxsulam 2% EC @ 500 ml ha -1 , (T2) Pyribenzoxim 3% + Penoxsulam 2% EC @ 750 ml ha -1 , (T3) Pyribenzoxim 3% + Penoxsulam 2% EC @ 1000 ml ha -1 , (T4) Pyribenzoxim 3% + Penoxsulam 2% EC @ 1500 ml ha -1 , (T5) Pyribenzoxim 5% EC @ 600 ml ha -1 , (T6) Penoxsulam 2.67% OD @ 1000 ml ha -1 , (T7) Bispyribac-Sodium 20% + Pyrazosulfuron Ethyl 15% WDG @ 100 g ha -1 , (T8) Triafamone 20% + Ethoxysulfuron 10% WG @ 225 g ha -1 , (T9) Hand weeding at 30 and 60 DAT and (T10) Weedy check (Untreated). The results of the experiment showed that the application of post emergence herbicide Pyribenzoxim 3% + Penoxsulam 2% EC @ 1500 ml ha -1 has positive effect on growth and yield of rice. Significantly higher values of growth attributes such as plant height (cm), number of tillers hill -1 , dry matter accumulation hill -1 (g) were observed with treatment (T4) Pyribenzoxim 3% + Penoxsulam 2% EC @ 1500 ml ha -1 at 60, 90 and 120 DAT and at harvest stage as compared to other treatments whereas, least values were recorded with treatment (T10) Weedy check. Significantly higher grain yield (4050.55 kg ha -1 ) and straw yield (5524.62 kg ha -1 ) was observed with treatment (T4) Pyribenzoxim 3% + Penoxsulam 2% EC @ 1500 ml ha -1 and lower grain and straw yield was observed with treatment (T10) Weedy check.

A field experiment was conducted at Rice Research Centre, Agriculture Research Institute, Rajendranagar, Hyderabad during kharif, (2022) to assess the post emergence herbicide efficacy for drone spraying in transplanted rice (Oryza sativa L.). The experiment was laid out in randomized block design with 7 treatments and replicated thrice. Results revealed that among different doses of herbicidal treatments, post emergence application of penoxsulam 1.02% + cyhalofop-butyl 5.1% OD @ 180 g a.i ha-1using drone recorded highest number of tillers at harvest, plant height at harvest, number of panicles at harvest, grain yield and low weed dry matter at 60 DAT. It was statistically on par with application of penoxsulam 1.02% + cyhalofop-butyl 5.1% OD @ 120 g a.i ha-1 using knapsack sprayer, application of penoxsulam 1.02% + cyhalofop-butyl 5.1% OD @ 150 g a.i ha-1 using drone, and application of penoxsulam 1.02% + cyhalofop-butyl 5.1% OD @ 120 g a.i ha-1 using drone followed by application of penoxsulam 1.02% + cyhalofop-butyl 5.1% OD @ 90 g a.i ha-1 using drone followed by unweeded control.

“…Penoxsulam effectively controls Echinochloa crus-galli, Leptochloa chinensis, and annual Cyperaceae weeds, and it is effective against many broad-leaved weeds [28]. At present, the research on penoxsulam mainly focuses on its effect on rice safety and weed control in paddy fields [29,30].…”

Foxtail millet planting has a long history and profound role in agricultural civilization. However, weeds have become one of the obstacles restricting the development of the foxtail millet industry. Penoxsulam, as an early post-emergence herbicide for controlling gramineous weeds in paddy fields, is effective for some broadleaf weeds. In this study, six different doses (CK, 0.5X, 1X, 2X, 3X, 4X) of penoxsulam were sprayed at the 3–5 leaf stage of the conventional variety Jingu 21 to study its effect on the growth and development of foxtail millet, in order to screen out the appropriate spraying concentration. The main results are as follows: Within 15 days after spraying penoxsulam, the plant height and leaf area of foxtail millet decreased with the increase in spraying dose, and gradually recovered 15–25 days after spraying, but there were still significant differences compared with CK. The photosynthetic pigment content, net photosynthetic rate (Pn), transpiration rate (Tr), stomatal conductance (Gs), the maximum photochemical efficiency (Fv/Fm), photosynthetic system II actual photochemical efficiency (Y(II)), and photochemical quenching coefficient (qP) of foxtail millet decreased with an increase in the penoxsulam spraying dose, while the intercellular CO2 concentration (Ci) and non-photochemical quenching coefficient (NPQ) showed an upward trend. There was almost no significant difference in each index between the spraying dose of 0.5X and 1X and CK, but the photosynthesis of foxtail millet leaves was still significantly inhibited under a spraying dose of 3X and 4X. Penoxsulam had certain growth-inhibiting effects on Echinochloa crus-galli (L.) Beauv. (E. crus-galli), Digitaria sanguinalis (L.) Scop. (D. sanguinalis), Chenopodium album L. (C. album), and Amaranthus retroflexus L. (A. retroflexus) which increased as the spraying dosage increased. Our study found that spraying dose groups of 0.5X and 1X penoxsulam were safe for foxtail millet growth and could be used to control gramineous weeds in fields. Other spraying doses are not recommended in the field due to their serious phytotoxicity to foxtail millet, which provides a new measure for weed control in foxtail millet fields.
