Essential oil of Chrysanthemum indicum L.: potential biocontrol agent against plant pathogen Phytophthora nicotianae

Abstract

Phytophthora nicotianae is currently considered one of the most devastating oomycete plant pathogens, and its control frequently relies solely on the use of systemic fungicides. There is an urgent need to find environment-friendly control techniques. This study examined the chemical composition, inhibitory activity, and possible modes of action of the essential oil of Chrysanthemum indicum L. (EOC) flower heads against P. nicotianae. The EOC was obtained using hydrodistillation at a 0.15% yielded. It inhibited mycelial growth and spore germination of P. nicotianae at a minimum inhibitory concentration (MIC) of 200 μL/L, and exhibited fumigation effects (92.68% inhibition at 157.48 μL/L). Marked deformation of P. nicotianae mycelia included deformed tip enlargement, shrinkage, and rupture. Further, 55 and 47 compounds were identified using gas chromatography-mass spectrometry (GC-MS) and headspace solid-phase microextraction (HS-SPME) GC-MS analyses, representing 88.2% and 98.91% of the total EOC, respectively. Monoterpenes (25.77%) and sesquiterpenes (54.14%) were the major components identified using GC-MS, whereas monoterpenes were the main constituents in the HS-SPME GC-MS analysis. The higher proportions of sesquiterpenes and monoterpenes could be responsible for the inhibitory activity of EOC, which increased mycelia membrane permeability and the content of mycelial malondialdehyde (MDA) in a dose-dependent manner. Cell death also occurred. Thus, destruction of the cell wall and membrane might be two modes of action of EOC. Our results would be useful for the development of a new plant source of fungicide for P. nicotianae-induced disease.

Antarctic Losing Tiny Amounts Of Ice (Or Maybe It’s Gaining Ice, NASA Is Not Sure!)

By Paul Homewood

 

h/t AC Osborn

 

Another mindbendingly naive piece by the Mail's Joe Pinkstone:

 

Antarctica is shedding ice at a staggering rate.

Scientists have discovered global warming has caused the melting of the ice on the continent to increase sixfold since 1979.

This phenomenal rate of melting has seen global sea levels rise by more than half an inch – and experts predict it will get worse. 

Scientists have predicted a 'multi-meter sea level rise from Antarctica in the coming centuries' as a result of the vast loss of ice.

Researchers discovered that, between 1970 and 1990, the continent was shedding an average of 40 gigatons of ice mass annually.

This jumped to an average of 252 gigatons a year between 2009 and 2017. 

https://www.dailymail.co.uk/sciencetech/article-6590841/Antarctica-losing-SIX-TIMES-ice-year-1970s.html#newcomment

 

You may of course recall that it was only three years ago that the same NASA, who are behind this latest scare story, were telling us that the ice cap was actually growing in Antarctica. But more of that in a minute.

There are several aspects to this latest story that need closer examination.

Firstly, according to NASA's own press release, the study only looks at data since 1992. The Mail's headline that "Antarctica is losing SIX TIMES more ice a year than it was in the 1970s " is totally fake, as there is no data for the 1970s. Any estimates of ice loss in the 1970s and 80s are pure guesswork, and have never been part of this NASA IMBIE study, or previous ones.

Secondly, the period since 1992 is a ridiculously short period on which to base any meaningful conclusions at all. Changes over the period may well be due to natural, short term fluctuations, for instance ocean cycles. We know, as the NASA study states, that ice loss in West Antarctica is mainly due to the inflow of warmer seas.

The eruption of Pinatubo in 1991 is another factor. Global temperatures fell during the next five years, and may well have slowed down ice melt.

Either way, Pinkstone's claim that the ice loss is due to global warming is fake. It is a change in ocean current that is responsible, and nothing to do with global warming.

Then there is his pathetic claim that "Antarctica is shedding ice at a staggering rate". Alarmist scientists, and gullible reporters, love to quote impressive sounding numbers, like 252 gigatons a year. In fact, as NASA point out, the effect on sea level rise since 1992 is a mere 7.6mm, equivalent to 30mm/century.

Given that global sea levels have risen no faster since 1992 than they did in the mid 20thC, there is no evidence that Antarctica is losing ice any faster than then. To call it staggering is infantile.

NASA also reckon that ice losses from Antarctica between 2012 and 2017 increased sea levels by 3mm, equivalent to 60mm/century. Again hardly a scary figure. But again we must be very careful about drawing conclusions from such a short period of time. Since 2012, we have had a record 2-year long El Nino. What effect has this had? 

But back to that previous NASA study, carried out by Jay Zwally in 2015, which found:

A new NASA study says that an increase in Antarctic snow accumulation that began 10,000 years ago is currently adding enough ice to the continent to outweigh the increased losses from its thinning glaciers.

The research challenges the conclusions of other studies, including the Intergovernmental Panel on Climate Change's (IPCC) 2013 report, which says that Antarctica is overall losing land ice.

According to the new analysis of satellite data, the Antarctic ice sheet showed a net gain of 112 billion tons of ice a year from 1992 to 2001. That net gain slowed   to 82 billion tons of ice per year between 2003 and 2008.

https://www.nasa.gov/feature/goddard/nasa-study-mass-gains-of-antarctic-ice-sheet-greater-than-losses 

Far from losing ice, as the new study thinks, Zwally's 2015 analysis found the opposite, that the ice sheet was growing.

OK, Zwally's data only went up to 2008, but there are still huge differences. Whereas Zwally estimates ice gain of between 82 and 112 billion tonnes a year between 1992 and 2008, the new effort guesses at a loss of 83 billion tonnes a year.

It is worth pointing out that Zwally's comment about the IPCC 2013 report refers to the 2012 IMBIE report, which was the forerunner to the new study, the 2018 IMBIE.

Quite simply, nobody has the faintest idea whether the ice cap is growing or shrinking, never mind by how much, as the error margins and uncertainties are so huge.

The best guide to such matters comes from tide gauges around the world. And these continue to show that sea levels are rising no faster then mid 20thC, and at a rate of around 8 inches per century.

Swiss Daily NZZ: More Than 1000 Citizen Wind Energy Protest Groups …Germany “On Path To The Unknown”

Although resistance to littering the landscape with industrial wind turbines continues to grow strongly, the German government refuses to back off its expansion of wind energy and solar.

Protests groups reach over 1000 in number as wind turbine litter the German landscape. Photo: Windwahn.

Jonas Herrmann of the Swiss NZZ here comments how Germany "is struggling with its wind turbines".

It started 28 years ago, when the German government enacted a law that forced power companies to buy up any green power produced, pay exorbitant prices for it and feed it into the power grid whether it was needed or not. Over time the installation of solar panels and wind turbines exploded and today many parts of the countryside have become littered with unsightly wind parks.

Ruined landscape, yet a long way to go

Yet, Germany today remains far away from supplying its energy needs through "green" sources.

The NZZ comments: "The landscape has changed in many places as a result. A longer drive through Germany inevitably leads past dozens of wind turbines."

Moreover, every community has been impacted, Nikolai Ziegler, says the chairman of resistance group Vernunftkraft, which is the major umbrella association of wind power opponents. According to Ziegler: "In Germany there are more than 1000 citizens' initiatives that are mobilizing against wind energy" and that these groups are getting involved in politics.

Wind and sun will never be able to do the job

Not only are wind turbines ruining Germany's idyllic landscape, but the NZZ writes that much of the resistance is also based on wind energy's technical unreliability as a power supply. The Herrmann at NZZ cites engineering expert Dr. Detlef Ahlborn, who says wind energy is too erratic and thus unreliable.

According to the NZZ;

With the umbrella organization Vernunftkraft, everyone is convinced that wind and solar energy will never be able to ensure a secure power supply."

Proponents in denial

This is a claim that the German government and green energy proponents refuse to acknowledge. Proponents in Germany believe that the problems with green energies will somehow go away and the supply will miraculously somehow smooth out if more and more volatile wind and sun capacity gets installed.

Critics like Nikolai Ziegler also criticize that there really hasn't even been any real Energiewende (transition the green energies) so far because electricity is only one fifth of Germany's total energy demand. Green energies provide only one third of that one measly fifth, and so "it's relatively meaningless".

The NZZ notes that "most of the leaders of the protest group Vernunftkraft are "male in the second half of their lives" who "are united by their anger at wind energy", but adds most have a background in natural science almost half of them are professors.

"Path to the unknown"

Vernunftkraft is calling for an end to green energy subsidies, a stop to the construction of additional wind turbines and instead greater investment in gas-fired power plants

The NZZ writes:

However, a political majority is not in sight. Although the AfD and parts of the FDP [parties] believe the Energiewende is a mistake, the German government can hardly prevent a further expansion of renewable energies. Germany is thus still on the path to the unknown with the Energiewende."
