“…The lowest dehydrogenase activity was recorded in pre emergence application of atrazine 1.25 kg ha -1 . Significantly higher dehydrogenase activity was observed in weed free and weedy check in maize, followed by tank-mixtures of topramezone 12.5 g ha -1 + 2,4-D 500 g ha -1 and tembotrione 50 g ha -1 + 2,4-D 500 g ha -1 at 7 and 14 days after herbicide application, while the lowest was with atrazine 1 kg ha -1 (Varshitha et al, 2019). Post emergence application of tembotrione 105 g ha -1 at 15 DAS increased the urease activity from 0 days after treatment (11.45) to 45 days after treatment (14.15) and there after decreased till harvest, whereas on the other hand, application of topramezone + atrazine 25.2 + 250 g ha -1 increased urease activity from 0 to 15 DAT and later decreased till harvest of maize (Aruna et al, 2018).…”

In India the highest loss (33%) is caused by weeds, followed by pathogens (26%), insects (20%), storage pests (7%), rodents (6%) and others (8%). Weeds compete with the crop for both above and below ground resources. Critical period of weed competition starts from 17 to 29 days after planting of corn, at an acceptable yield loss of 5 to 10 per cent. Herbicides are efficient tools for checking weed infestation and its usage is increasing throughout the globe due to increasing labour cost and quick weed control in various situations. The common weed management practice for Maize is pre-emergence application of selective herbicides like atrazine or pendimethalin followed by one hand weeding. Managing weeds through pre-emergence, post-emergence and sequential use of herbicides will be an ideal means for controlling the weeds in the view of economics and effectiveness in maize.

“…Lal et al [85] observed that weed free check recorded significantly higher dehydrogenase, urease and phosphatase activity at 7 and 15 days after spraying compared to all other treatments and lower dehydrogenase, urease and phosphatase activity under imazethapyr (75 g ha -1 with adjuvant) application at 7 and 15 days after spraying in green gram. Significant increase in dehydrogenase activity of all the treatments at 50 days after herbicide spray i.e., peak period of crop growth was observed indicating that microbial activity was increased in maize [86].…”

Mustard (Brassica juncea L.), a species of the cruciferous family, is the world's third most significant oilseed crop, following soybean and palm. Mustard seeds range in oil content from 37 to 49%. India is the fourth-largest producer of mustard and rapeseed in the world. The most significant issue causing mustard's low yield is weed control. Crop yields are significantly reduced by weeds; in the case of mustard, this can mean a complete failure rate of 15–30%. Crop plants compete with weeds for nutrients, sunlight, space, and water. In addition to lowering crop quality, weeds pose a number of nutritional and environmental hazards. In mustard crops, weed competition is particularly important in the early stages since the crop grows slowly in the first 4–8 weeks after sowing. On the other hand, 15–40 days are the critical window for crop–weed competition. Weed control must be carried out appropriately and on time in order to maximize mustard growth and production. During the early stages of crop growth, 25–30 days after sowing, the traditional practice of hand weeding once is insufficient because weeds always reappear after manual weeding, irrigation, or winter rainfall. More importantly, though, is that these weeds drain a large amount of the soil's moisture and nutrients. Though hand weeding mustard is simple, the expense of doing so is significant due to the scarcity of labor at the appropriate time and the uncontrolled growth of various intra row weeds. Weeds may become tolerant of herbicides despite their regular and high dosage application. Therefore, combined approaches could be the best option to control the complex weed flora in mustard.
