Pyroxasulfone is an experimental herbicide for use in field corn (Zea mays L.) and soybean that may have potential for weed management in sweet corn. Tolerance of eight sweet corn hybrids to pyroxasulfone applied preemergence (PRE) at rates of 0, 209, and 418 g·ha−1 a.i. were studied at two Ontario locations in 2005 and 2006. Pyroxasulfone applied PRE at 209 and 418 g·ha−1 caused minimal (less than 3%) injury in Harvest Gold, GH2041, GH9589, GSS9299, GG214, GG446, GG763, and GG447 sweet corn hybrids at 7, 14, and 28 days after emergence. Pyroxasulfone applied PRE did not reduce plant height, cob size, or yield of any of the sweet corn hybrids tested in this study. Based on these results, pyroxasulfone applied PRE at the rates evaluated can be safely used for weed management in Harvest Gold, GH2041, GH9589, GSS9299, GG214, GG446, GG763, and GG447 sweet corn.

Initial Sensitivity

Topramezone is a newly introduced herbicide for use in field corn (Zea mays L.) that may have potential for weed management in sweet corn. Tolerance of eight sweet corn hybrids to topramezone applied postemergence (POST) at 0, 50, 75, 100, 150, and 300 g a.i. ha− 1 were studied at one Ontario location in 2000 and two locations in 2001 and 2002. Topramezone applied POST at 50, 75, 100, and 150 g·ha− 1 did not cause any visual injury in Calico Belle, CNS 710, Delmonte 2038, FTF 222, FTF 246, GH 2684, Reveille, and Rival sweet corn hybrids at 7 days after treatment (DAT) and caused minimal injury (less than 5%) at 300 g·ha− 1 in all hybrids. The initial sensitivity observed in these hybrids was minimal and transient with no effect on visual injury at 14 and 28 DAT. Topramezone applied POST did not reduce plant height, cob size, or marketable yield of the sweet corn hybrids included in this study. Based on these results, topramezone applied POST at the rates evaluated can be safely applied to Calico Belle, CNS 710, Delmonte 2038, FTF 222, FTF 246, GH 2684, Reveille, and Rival sweet corn.

A field experiment entitled, “Integrated weed management in Kharif maize (Zea mays L.)” was conducted during Kharif, 2020 at Post Graduate Research Farm, RCSM College of Agriculture, Kolhapur. The experiment was laid out in Randomized Block Design (RBD) having three replications and twelve treatments. The soil of the experimental plot was medium black clay (vertisol) with 90 cm depth, low in available N (250 kg ha-1), high in available P2O5 (30.60 kg ha-1) and medium in available K2O (290.67 kg ha- 1). The status of organic carbon content (0.34%) was low. The electrical conductivity and pH values were 4.2 dSm-1 and 7.10, respectively.Weed free check and tank mixure application of Tembotrinone 42 SC @ 120gm a.i.ha-1 + Atrazine 50 WP @ 500 gm a.i.ha-1 + surfactant @ 2ml/l of water EPoE At 20-25 DAS + fb hand weeding at 40 DAS were on par with each other and recorded significantly the higher growth and yield contributing characters viz., plant height (cm), number of functional leaves plant-1, leaf area plant-1(dm2), dry matter plant-1(g), length of cob (cm), diameter of cob(cm), number of grains, weight of grains cob-1and test weight resulting into significant increase in grain and straw yields of maize as compared to remaining weed management treatments. Tank mixure application of Tembotrinone 42 SC @ 120gm a.i.ha-1 + Atrazine 50 WP @ 500 gm a.i.ha-1 + surfactant @ 2ml/l of water EPoE At 20-25 DAS + fb hand weeding at 40 DAS recorded minimum dry weight of weed, highest weed control efficiency (86.94 %) and lowest weed index (1.79%).Significantly lowest values for growth, yield and yield attributes as well as weed control efficiency was observed in weedy check treatment.

Sweet corn [Zea mays (L.) var. saccharata strut] is the most important variety of maize with high sugar content. It contains a glossy sweetish endosperm and primarily grown for human food. It requires moderately high temperature from 22oC up to 33oC, high light intensity and adequate and well distributed rainfall of not less than 200mm during growing season. It can be grown on the wide range of soils. However, it performs best on neutral, well drained, well aerated and moderately heavy, deep fertile soils. Sweet corn is not so much competing with weeds like other crops. Avoid the influence of weed competition on the growth and development of sweet corn produce maximum yield and the economic importance of sweet corn used for conception and health benefits. By so far it is good in health and as medicinal uses it should be managed without affecting by weeds. The weed management option properly controls by the method of mechanical, biological, chemical and integrated weed management. In general, it is significant that properly controlling critical period weed competition in sweet corn reducing the competition of light, water, nutrient and space and maximizing the yield of sweet corn.
