The Western Lake Erie impaired waters saga continues

first_imgShare Facebook Twitter Google + LinkedIn Pinterest The Ohio EPA has released its draft water quality report for 2018 and the report proposes to list the open waters of the Western Basin of Lake Erie as “impaired.” The road to this listing has been long and complicated.The controversy began in the fall of 2016, when Michigan and Ohio submitted their respective impaired waters lists to the U.S. EPA. Every two years, a regulation promulgated under the Clean Water Act requires states to turn in a list of their impaired waters. Michigan listed the waters of Lake Erie under its jurisdiction as impaired, while Ohio did not list the open waters in the Western Basin of Lake Erie as impaired. The waters described by Michigan as impaired and those not listed by Ohio are basically one in the same, hence the problem. The U.S. EPA approved Michigan’s list in early 2017, but made no decisions about Ohio’s list.As a result of the discrepancy over Lake Erie, environmental and other groups sued the U.S. EPA to make a decision about Ohio’s impaired waters list. On May 18, 2017, the U.S. EPA approved Ohio’s list. However, on Jan. 12, 2018, the U.S. EPA withdrew its earlier approval and asked Ohio to compile additional data for a new evaluation of the status of the Western Basin of Lake Erie.With all of this back and forth and litigation, it is now long past the due date for the 2016 impaired waters list. As a result, the draft water quality report submitted by the Ohio EPA on March 22 contains the 2018 list. Ohio EPA’s 2018 draft water quality reportIn its draft water quality report, the Ohio EPA outlines the general condition of Ohio’s waters and lists “impaired waters” that are not meeting federal or state water quality goals and waters that have improved to meet water quality standards. For the first time, the EPA includes the open waters in the Western Basin of Lake Erie on its impaired list. The impaired designation is for recreational uses “due to harmful algae” and for drinking water “due to occurrences of microcystin.” (Microcystin are harmful toxins created by blue-green algae. More information about these toxins is here.) Other new areas listed as impaired for drinking water due to harmful algae are Sims Run, parts of the Maumee River, the headwaters to Grand River and the headwaters of Cowan Creek in the Little Miami River watershed. Next steps and public commentsWhile an impaired listing may not create immediate change in the Western Basin, it will require Ohio to create total maximum daily loads, which are the amounts of different pollutants allowed to be discharged each day in the open waters. This could eventually mean increased regulation of certain pollutants in the area, which may include agricultural nutrients such as phosphorous and nitrogen. Only time will tell.The EPA is accepting written comments on its proposed list of impaired waters. Submit comments by May 4, 2018, to [email protected], or to Ohio EPA Division of Surface Water, P.O. Box 1049, Columbus, Ohio 43216-1049, attn: 303(d) comments. Following public review and comments, the agency will submit a final report to the U.S. EPA. The agency published a news release on the draft water quality report and is hosting an upcoming webinar on the report on April 25, 2018.Read the EPA’s draft water quality report here.last_img read more

Fungicide considerations in corn

first_imgShare Facebook Twitter Google + LinkedIn Pinterest By Luke Schulte, Beck’s HybridsWhile it may seem far off, soon it will be time to make crop evaluations to determine whether or not to apply a fungicide application to your tasseling corn crop. As of today, several major yield determining growth stages have already passed. Emergence and potential ear size have been determined and pollination (actual kernel number) will take place very soon. The primary function of the corn plant post-pollination is to minimize kernel abortion and maximize kernel depth and weight. Many things can impact these three outcomes but nutrient availability, moisture, and sunlight capture are the most significant.Many of the fungicide products available today consist of a class of fungicides known as strobilurins. These “strobi” class of fungicides provides multiple benefits. For many farmers, fungicides are considered mainly for their role in mitigating disease. While strobis do provide systemic activity on disease, they also help reduce respiration. Reducing respiration leads to several beneficial outcomes including improved stress tolerance and increased efficiency of the plant’s physiological processes. This results in improved water-use efficiency and increased activity of nitrate reductase, the enzyme that makes a form of nitrogen that can be used by the corn plant. Both of these will have a significant impact on kernel retention, kernel depth and ultimately, yield.Corn hybrids vary in terms of plant intactness and staygreen as they mature or move towards senescence. Generally speaking, the greener a hybrid remains as it nears maturity, the better the standability, test weight and yield. Preventing the loss of leaf area to disease increases our overall solar panel to harvest more sunlight. Some hybrids also have a tendency to die prematurely, which is often a result of fungi invading the plant from the root system and traveling up the plant. Wetter, saturated soils tend to have increased populations of these fungal pathogens. Fungicides applied at tassel can reduce the severity of early plant death while also allowing the plant to mature more naturally. The longer a corn plant can continue to harvest sunlight, the more energy it can generate to drive yield.Consider the following when evaluating your need for an at-tassel fungicide application:Hybrid ResponseOverall disease ratingStaygreen ratingPremature death or the hybrid’s tendency to die early (preventative approach)Yield potential – A racehorse hybrid will likely be more responsive than a workhorseDisease PressureScout/observe two leaves below the ear leaf and the above portion of the plantForecast for Gray Leaf Spot (GLS) — when temperatures range between 75 degrees to 85 degrees F, spore reproduction occurs every two to three weeks. Forecast for Northern Corn Leaf Blight — when temperatures range from 64 degrees to 81 degrees F, spore reproduction occurs every six to eight days.EnvironmentResidue in a corn after corn rotation = increased fungal inoculumAir movement, bottom areasWetter soils cause an increased risk of PMDNitrogen deficient.AdjuvantsCan help with penetration of the canopy and coveragePrior to full tassel (uneven fields) do not use adjuvants containing NPE, which is a compound found in some adjuvants that can lead to arrested ear development. InsecticidesPrimary objective is to control silk clippers such as Japanese beetles, CRW beetles, etc.If moisture is not limiting, then an insecticide will likely not be necessary.If you have concluded that a fungicide is warranted, the last item to address is which product to use? Beck’s Practical Farm Research (PFR) team has tested many fungicide products over the years, but the fungicides that have resulted in the highest ROI have been those that provide the greatest length of activity. Each of these fungicides (shown below) contains multiple fungicide classifications, including a strobilurin.last_img read more

Pakistan won’t attempt another Kargil: Army Chief

first_imgPakistan will not attempt another Kargil-like infiltration as it has “seen the consequences”, Army Chief General Bipin Rawat said on Friday as India commemorates 20 years of the conflict this year.“We don’t think Pakistan will attempt something like that because they have seen the consequences…I can clearly say, in the coming days and years, Pakistan will not dare to attempt any infiltration,” Gen. Rawat said in response to a question. “There is no such area that we have left unguarded. Our surveillance team is keeping a tight watch and regularly patrolling the areas,” he stated.The Army Chief was speaking to the media on the sidelines of a commemorative event on Kargil where he released a video of a special tribute song penned by Bollywood lyricist Sameer, dedicated to the Kargil heroes.Army GamesLater, Gen. Rawat attended a curtain raiser event for the International Army Games, part of which is scheduled to take place at Jaisalmer in August. This is the fifth edition of the games and India is hosting the International Scout Masters Competition for the first time. The Army games are organised by the Ministry of Defence of the Russian Federation.last_img read more

Gambhir slams ton again; India win series

first_imgSkipper Gautam Gambhir hit his second unbeaten century to power India to a series-clinching nine-wicket victory over New Zealand in the third ODI in Vadodara on Saturday.Gautam Gambhir celebrates after scoring fifty during the third ODI against New Zealand in Vadodara. Photo by APThe Delhi left-hander played a captain’s knock of 126 after his match-winning unbeaten 138 in the second ODI in Jaipur on December 1 as India easily chased down the target of 225 in 39.3 overs to take an unassailable 3-0 lead in the five-match series.Gambhir, who smashed 16 boundaries in 117 balls, piled up 115 runs for the opening wicket with Murali Vijay who made a slow 30 in 50 balls before being run out.The solid foundation laid by Gambhir, who notched up his ninth ODI hundred in 103 matches, with Vijay was carried forward by the next batsman, Virat Kohli, who continued his form from where he left in the previous two matches.Virat Kohli in action.

Gambhir raced to his 50 in just 30 balls with nine fours and then got his next 50 in 58 balls with the help of four fours.He struck left arm Andy McKay for three successive fours after having dispatched the other new ball bowler Kyle Mills for two in as many balls previously.Gautam Gambhir bats before New Zealand’s wicketkeeper Gareth Hopkins.

Photo by APLeft-handed Franklin batted sensibly after coming in at 49 for 4 in the 16th over even as continued to tumble from the other end. He top-scored for the Black Caps with the help of five fours and one six in 108 balls while McCullum made 43 in 53 balls with four fours. Their eighth-wicket stand off 107 balls took the score to 200 after the Kiwis had lost half their side for 77.Apart from the eighth wicket pair, only opener Martin Guptill (12) and Scott Styris (22) reached the double figures in a largely uninspiring display put up by the Kiwis after they were asked to bat first by the hosts.Indians bowl tight lineFor India, Zaheer Khan (2/31), Yusuf Pathan (2/37 and R. Ashwin (2/49) shared six wickets among them while Munaf Patel chipped in with one scalp.The pitch for the match was a major surprise at a venue that normally provides flat tracks. There was a lot of bounce for the pace bowlers and bounce and turn for the spinners.New Zealand batsmen, having played on low bouncing tracks after coming to India in early November, were undone by the extra bounce. Zaheer utilized the bounce to the fullest extent in his splendid first spell of seven overs as he made early inroads into the Kiwi top order. Coming off after a three-week lay-off, the left-arm paceman struck in the second legal ball of his first over when he prised out danger man Brendon McCullum, who also came into the series after missing the opening two ties because of a back problem.advertisementMcCullum was caught in second slip by Murali off a rising ball that moved away a shade. Munaf bowled tightly to return with one for 28 while spinners Yusuf Pathan and Ashwin did their but in the middle overs to claim 2 for 27 and 2 for 49 respectively.- With PTI inputslast_img read more
