Watch fields for black cutworms

first_imgShare Facebook Twitter Google + LinkedIn Pinterest Black Cutworm moths are starting to arrive in the Corn Belt with the recent weather fronts moving from southwest and we need to be ready with the rescue treatments, if necessary. We need to learn about their habits and what to look for while scouting. Some of the important points are as follows:• Black cutworms can’t survive the winters in the Midwest. They fly south before the winter arrives.• Every spring, moths come back with spring storms and lay eggs on grasses and weeds like mustards, chickweed or even winter wheat.• From egg hatching to becoming adults it takes 40-50 days depending on temperatures. Even though cooler temperatures earlier may have killed some of the moths, warmer temperatures that followed increased the speed up their development and more will come. Some cutting activity has already been observed in Southern Illinois.• Corn and soybeans are not their favorite hosts. When weeds are destroyed, larvae start feeding on corn. Small larvae feed on leaves. If you see small, irregular holes in the leaves, start looking for cutworms.• Black cutworms feed above ground until they are about half inch long. It takes three instars to get to that stage. Each instar needs 100- 140 growing degrees.• After about 300-400 accumulated GDs, at the fourth instar, watch out! Now these enemies of our corn crop are ready to do real damage and start cutting plants at or below ground level.• Black cutworms are clever bugs. They hide during the day and feed at night. Scout your fields at least once a week and use suitable foliar insecticides, if needed, otherwise they might do serious damage to your crops.• According to Purdue Entomologist, John Obermeyer, don’t think you are in the clear just because you have the insecticide coated seed because there are different levels of the coatings and lower levels may not provide full protection. His advice is to scout your fields and rescue your crops if needed. 
If your crop is under attack, good offence may be the best defense!last_img read more

Generating Electricity from the Sun

first_imgAlmost all of our methods for generating electricity are fundamentally the same. Coal-, nuclear-, and natural-gas-fired power plants boil water to produce high-pressure steam that spins a dynamo in a “steam turbine.” The wood-chip-fired combined-heat-and-power (CHP) plant that we want to build in Brattleboro works the same way. The heat sources used in these systems, of course, are very different—each with its own environmental and health concerns—but the way they actually produce the electricity is, fundamentally, the same. Hydro power plants use the gravitational force of flowing water to spin a similar turbine, and windmills use the power of wind to do the same thing.There’s only one fundamentally different power-generation technology that’s feeding a significant amount of electricity into the utility grid: photovoltaics, or the direct conversion of sunlight into electricity. Photovoltaic (PV) cells, remarkably, produce electricity with no moving parts. There’s no mechanical gearing to lubricate or wear out, essentially nothing to maintain. They just sit there, in the sun, and generate direct-current electrical energy.While simple in their effect, how PV cells work is quite complex. Here’s an oversimplification of the process: A PV cell is made of a “semiconductor” material, such as silicon—semiconductors are materials whose electrical conductivity can be changed by adding small amounts of impurities. In a typical silicon PV cell, there are two layers of slightly different silicon, separated by a “cell junction.” On one side of the cell, the silicon wants to get rid of electrons; the other side wants electrons.When photons of light strike the cell, the electrons in the silicon become energized, and some of them jump across the cell junction—but they con only cross that junction one way. As a result a charge differential is created, with more electrons (electrical charge) on one side of the cell than the other. By connecting a wire to the cell, this charge differential can be equalized by allowing the electrons to flow through the wire. This flow of electrons is direct-current (DC) electricity, and we can tap into that current to perform work—powering motors, producing light, etc.PV cells are wired together into “PV modules” so that the small amounts of current created by each cell are aggregated into useful quantities of electrical power. The modules, in turn, are often combined into “PV arrays”—sometimes huge arrays that generate many kilowatts or even megawatts of electricity when the sun is shining.Finally, inverters convert the DC electricity into alternating current (AC) that can operate standard electrical devices or be fed into the power grid using special equipment.The practical photovoltaic cell was invented in the 1950s by scientists at Bell Laboratories in New York. Initially, the cost was extremely high—thousands of dollars per peak watt of output. The first applications for PV were on space satellites where that high cost was not a concern. In fact, local PV expert Richard Gottlieb of Sunnyside Solar in Guilford, VT, worked at the Naval Research Laboratory installing PV cells on the Vanguard satellite as a college student in 1957.As the manufacturing of PV modules was streamlined and the cell efficiencies improved, costs came down. By the 1970s, PV power became practical for applications like remote radio repeater stations and Coast Guard signal buoys. In 1983, I organized a conference for the Northeast Sustainable Energy Association, “Photovoltaics: From Research to Reality,” which was held at MIT in Cambridge. By then, some pioneering designers were incorporating PV arrays into houses. Steven Strong, of Solar Design Associates in Harvard, MA, designed some of the first such homes, and he continues to be a leading designer of PV-powered homes.Today, there are tens of thousands of homes throughout the country that derive a significant portion—sometimes all—of their electricity from PV arrays. Many of these are “off-grid” homes that are totally independent of utility power. They have battery banks so that lighting and other electrical devices can be used at night or during very cloudy periods. There are dozens of such homes in the Brattleboro area.Other homes with PV power are “grid-connected.” Rather than batteries, these homes have “net-metering” systems that feed electricity into the grid when the sun is shining and the PV system is producing more electricity than the house needs to operate. In states with net-metering laws, including Vermont, New Hampshire, New York, and Massachusetts, when the PV system is producing excess power the electric meter spins in reverse, and the utility company effectively pays you for that electricity at the same retail price you pay for electricity.Though PV costs have dropped a great deal since the 1980s, high first-cost remains an impediment to widespread use of PVs. For a grid-connected PV system (without batteries), installed costs today range from About $6,000 to $12,000 per peak kilowatt (kW) of capacity, before government incentives or tax credits. Thus, a 4.5 kW residential system, which would produce about as much electricity annually as a typical home uses, will cost in the range of $27,000 to over $50,000. Grid-connected PV systems are eligible for cash subsidies from the states of Vermont, New Hampshire, Massachusetts, Connecticut, and New York, as well as a 30% federal tax credit.For more information on costs and subsidies, contact an installer, such as Richard Gottlieb or one of the companies listed in last week’s column.last_img read more

Can King Kohli bring his overseas form to India?

first_imgAfter a very long time, Indian cricket fans have had the chance to witness the team register back-to-back series wins abroad. First it was Sri Lanka and then the West Indies. India have been on a roll ever since Virat Kohli took over the captaincy from Mahendra Singh Dhoni last year. (India historically a dominant force vs New Zealand: A stats preview)The captain himself has been in exceptional form with the bat and has lead with example. Kohli’s hunger for runs and attitude on the field has also rubbed off on his teammates. With the exception of Shikhar Dhawan and Rohit Sharma, all the other batsmen including the lower-order have performed superbly under their new captain. (ICC chairman Shashank Manohar congratulates BCCI for India’s 500th Test)Now with 13 Tests coming up in India in the next few months, the biggest challenge for Kohli will be to replicate his success with the bat and leadership on home soil. (Five reasons why New Zealand can stun fancied hosts in Kanpur)Kohli has been among the top-three run-getters on India’s last three tours which includes the recently concluded series in the West Indies and the Border-Gavaskar trophy which was played Down Under last year. The 27-year-old’s form on home soil though, has been ordinary. The upcoming three-match series against New Zealand will be a big test for Kohli on the rank turners in India as the Black Caps have three quality spinners in their side in Ish Sodhi, Mark Craig and Mitchell Santner. (Career defining season for Indian cricketers: Virat Kohli)advertisementKohli’s numbers since late 2014 till now on away tours have been phenomenal.INDIA IN WEST INDIES, 2016: FOUR-TEST SERIESHe scored 251 runs in three matches in the Caribbean at an average of 62.75 with a double hundred being his highest score on the tour. Kohli didn’t get to bat in the fourth match as rain washed out the match with West Indies on 62/2 in the first innings on Day 1. He still finished as the highest run-scorer from either side and was a close contender for the Player of the Series award until Ravichandran Ashwin beat him to it thanks to his overall performances.INDIA IN SRI LANKA, 2015: THREE-TEST SERIESIndia’s three-match Test series against Sri Lanka last year wasn’t as high-scoring due to the slow and turning pitches on offer in the island nation. It was also Kohli’s first full series as India’s captain. He averaged 38.83 on the tour, scoring 233 runs in 3 matches with a century and a fifty to his name. He was the highest run-scorer for India and third overall behind Lanka’s Angelo Mathews and Dinesh Chandimal.INDIA IN BANGLADESH, 2015: SOLITARY TESTIndia went to Bangladesh to play a lone Test match but that was affected by rain and Kohli managed just 14 runs in India’s first innings total of 462/6 declared.INDIA IN AUSTRALIA, 2014-15: BORDER-GAVASKAR TROPHYKohli scored 692 runs in 4 Tests in Australia at 86.50. (Reuters Photo)Kohli’s legacy as a modern great was cemented when India toured Australia in December 2014. The right-hander scored a mammoth 692 runs in four matches at a staggering average of 86.50 with four centuries and a fifty to his credit. This was also the series where Dhoni announced his retirement after the third Test in Melbourne and Kohli lead the team for the first time in the first and fourth Tests. He finished as the highest run-getter for India and second overall with only Australia captain Steve Smith overhauling Kohli’s tally with 769 runs at a mind boggling average of 128.16.On home soil though, Kohli hasn’t been able to perform at his absolute best in the longest format.INDIA vs SOUTH AFRICA, 2015: FREEDOM TROPHYKohli’s first full series as captain on home soil was a memorable one for the team but for him personally it wasn’t as impressive. He managed 200 runs in three matches at 33.33 with the second Test being washed out due to rain. Kohli scored just one half-century with his highest score being 88. His dismissals in the series in particular had no set pattern as he got out to pacers and spinners equal number of times.INDIA vs WEST INDIES, 2013: TWO-TEST SERIESSachin Tendulkar’s farewell series saw India register comfortable wins against an inexperienced West Indies side led by Darren Sammy. Kohli, just two years into his Test career, was a middle-order batsman then and used to come in after the Master Blaster at No. 5. He scored 60 runs from two games at an average of 30.00 in the series with 57 being his highest score.INDIA vs AUSTRALIA, 2012-13: BORDER-GAVASKAR TROPHYadvertisementThe high-scoring four-match series between India and Australia saw Kohli score 284 runs in four matches at a decent average of 56.80. Kohli played some crucial knocks in the middle-order along with Cheteshwar Pujara, MS Dhoni and finished the series as the fifth highest run-getter as India whitewashed the Aussies for the first time in Test history.last_img read more
