Prirodna zaštita biljaka

Objavljeno u Okoliš

Zaštita biljaka od gljivičnih oboljenja ili napada štetoćina vrši se iskljućivo sa biljnim srestvima. Bitno je da se biljke prskaju preventivno ili najkasnije kad se uoće prva oboljenja. Plodovi se jasno mogu i odmah jesti nakon prskanja.

BILJNA SREDSTVA ZA PRSKANJE

ČAJ OD POLJSKE PRESLICE (Equisetum arvense)

Taj čaj je jako dobro sredstvo za kontrolu gljivičnih oboljenja. Preslicu treba nabrati koncem ljeta ( 8 mjesec ) kada sadrži najveću količinu silicija te je osušiti na sjenovitom mjestu. Osušenu preslicu možemo upotrjebiti tijekom cijele godine. Čaj se koristi kao antigljivično sredstvo.

Čaj se priprema tako da se 300 grama suhe preslice kuha u 5 litara vode jedan sat na blagoj vatri. Nakon toga ga procjedimo i razrijedimo s još 25 litara vode. Prije upotrebe tekućina mora odstojati još 10 sati. Prilikom razrijeđivanja čaja potrebno ga je mješati oko 10 minuta.

Preporuča se jedno ili više prskanja vočaka nakon kišnog perioda i to prije ili u početku napada gljivičnih oboljenja. Prskati po sunčanom vremenu. Preventivno možemo prskati prema uputama " Mjesečnog sjetvenog kalendara ". Čaj od preslice može se dodavati i u vodi u kanti za zalijevanje , od njega pravimo i kupku za umakanje korjena prije sadnje voćaka. Prskamo po plodovima voćaka , krošnji i stablu.

Voćke prskanjem čajem od preslice dobivaju otpornost na pepelnicu , peronosporu , rđu i druga gljivična oboljenja.

Radi velike efikasnosti i suzbijanja raznih gljivičnih oboljenja farmeri kažu da im nikada nije dosta ove biljke.

Ja ovim čajem prskam lozu i povrće. Navedena kolićina čaja od 30 litara mi je dovoljna za prskanje 400 loza i 400 m2 povrtnjaka.

ČAJ OD STOLISNIKA (Achillea millefolium)

Stolisnik spada u narodnoj medicini među ljekovite biljke jer sadrži mirisnogorka eterična ulja i mnogo minerala. On ima i dezinfekciske osobine. Potiče i pospješuje djelovanje učinaka drugih biljaka te se zbog toga njegov čaj može mješati s drugim čajevima , a posebno to vrijedi za čaj od metvice i kamilice.

U ekovočarstvu koristi se kao sredstvo protiv pepelnice ,truleži plodova i drugih gljivičnih oboljenja.

Priprema se tako da 1 kg svježih listova , stabljika ( 15 cm dužine ) ili 200 grama suhog stolisnika shuhamo u 10 litara vode. To se procjedi i razrijedi s vodom u omjeru 5:1 i prskaju se oboljele voćke. Dodro je prskati preventivno ili čim se bolest primjeti. Najefikasnije je djelovanje ako se naprave čajevi od metvice i kamilice i pomješaju u istim omjerima s čajem od stolisnika.

Kod pojedinih voćaka može se pojaviti osip ( alergija na stolisnik ).U tom slučaju treba napustiti kontak biljkom i čajem od nje.

Ja ovim čajem prskam lozu i povrće. Sami odredite omjere i kolićinu potrebnog čaja.

SREDSTVO ZA PRSKANJE OD KOPRIVE (Urtica dioica)

Upotrebljava se za uništavanje mnogobrojnij lisnih uši , a istovremeno jača biljke,poboljšava im otpornost i gnjoji ih.

Priprema se tako da se 1 kg svježih , isječenih kopriva potopi u 10 litara vode i ostavi 24 sati. Ne duže jer preparat gubi moč. Ako nema svježih kopriva, na istu količinu vode treba uzeti 100 do 200 grama osušenih.Nakon 24 sata tečnost je potrebno procjediti i njome prskati biljke sa svih strana. Postupak se može ponoviti nakon nekoliko dana.Biljni ostaci se kompostiraju.

Važno je napomenuti da sredstvo za prskanje od koprive mora se upotrebiti nakon 24 sata , a nikako nakon 2 – 3 dana jer postaje agresivno i može spržiti biljke.

Ja ovim čajem prskam rijeđe lozu i češće povrće. Sami odredite omjere i kolićinu potrebnog čaja.

ČAJ OD PELINA (Artemisia absinthium)

Odlikuje se izrazitom gorčinom zbog čega ga izbjegavaju insekti. Priprema se tako da 300 grama predhodno osušenih i usitnjenih grančica pelina ( s listom , a može i s cvijetom ) prelije jednom litrom kipuće vode, ostavi stajati poklopljeno pola sata. Nakon toga se procjedi i doda 9 litara vode i čaj za prskanje je gotov. Čaj od pelina se koristi za zaštitu jagoda i kupina od grinja,protiv lisnih ušiju na svim voćkama , protiv gusjenica , mravi i drugih štetnih insekata.

Biljni ostaci se ne smiju kompostirati.

Ja ovim čajem prskam bob, fažolete , grašak i pomidore preventivno ili kad se pojave lisne uši.

Napomena:

Suha preslica, kopriva, te pelin, stolisnik, metvica i kamilica (sve u suhom stanju) mogu se nabaviti u Splitu u kiosku na tržnici iza starog igrališta Hajduka, svak po cijeni od cca 75 kn za 1 kg.

  • ‘When the hurricane hit, I saw my neighbour’s boat lift into the sky’ – This is climate breakdown

    All of a sudden I heard this loud noise at the back of my house. The window was smashed in what was supposed to be our secure room. This is Roseman’s story

    Location Union Island, the Caribbean

    Disaster Hurricane Beryl

    Roseman Adams, a nature conservation officer and part of the island’s disaster preparedness committee, was at home on Union Island when Hurricane Beryl hiton 2 July. It was the earliest-formingcategory 5 hurricane on record, demolishing almost all of the buildings on the island of 2,500 people. The climate crisis is making hurricanes ever more intense and destructive.

  • UK environment secretary vows to ensure farmers are paid fairly for produce

    Steve Reed says he may not agree on inheritance tax changes but government will listen to rural Britain

    The UK environment secretary has promised to reform the food system to ensure farmers are paid fairly for the food they produce, after many filled the streets of Westminster to campaign against inheritance tax changes.

    Speaking at the Country Land and Business Association (CLA) conference, Steve Reed said: “I heard the anguish of the countryside on the streets of London earlier this week. We may not agree over the inheritance tax changes, but this government is determined to listen to rural Britain and end its long decline.”

  • ‘The land is tearing itself apart’: life on a collapsing Arctic isle

    On Qikiqtaruk, off Canada, researchers at the frontier of climate change are seeing its rich ecology slide into the sea as melting permafrost ice leaves little behind

    Last summer, the western Arctic was uncomfortably hot. Smoke from Canada’s wildfires hung thick in the air, and swarms of mosquitoes searched for exposed skin. It was a maddening combination that left researchers on Qikiqtaruk, an island off the north coast of the Yukon, desperate for relief.

    And so on a late July afternoon, a team of Canadian scientists dived into the Beaufort Sea, bobbing and splashing in a sheltered bay for nearly two hours. Later, as they lay sprawled on a beach, huge chunks of the island they were studying slid into the ocean.

  • Call for east of England coast trail to address access-to-nature gap

    Exclusive: Trail would help region with few areas where people can walk in countryside, report says

    A new trail along the east coast of England should be created, a Tory thinktank has said, because farmland is preventing those who live there from having access to nature.

    A report from Onward has found that in most rural areas, people enjoy extensive rights-of-way networks. But across the east of England, there are many areas where people have barely anywhere they are allowed to walk in the countryside. This, the report says, is because of large areas of high-grade farmland in that area, but also because Lincolnshire has the largest backlog for recognition of historical but unrecorded rights of way, with more than 450 outstanding applications.

  • Human rights activists face reprisals for opposing extractive industries, says report

    Peace Brigades International calling for new act to force companies with links to UK to do due diligence

    Human rights defenders have faced brutal reprisals for standing up to extractive industries with links to UK companies or investors, according to a report calling for a law obliging firms to do human rights and environmental due diligence.

    Peace Brigades International (PBI) UK says a corporate accountability law requiring businesses to do due diligence on their operations, investments and supply chains could have prevented past environmental devastation and attacks.

  • A Bornean orangutan on a fearless quest for figs: Tim Laman’s best photograph

    ‘While it was dark, I climbed up and put remote control cameras in the tree. I’d never have got the shot if I’d been up there. An orangutan always knows you’re there’

    I was following orangutans in Borneo with my wife, Cheryl Knott, a primatologist who has spent 30 years working in Gunung Palung national park, in the Indonesian part of Borneo. I am a biologist by background, and did my PhD research in rainforest ecology in Borneo, before I went into photography and film-making. I saw so much destruction in the rainforest back in the 90s, and it dawned on me that I could publish scientific articles that maybe 10 people would read – or an article in National Geographic that 10 million people would see.

    I was getting increasingly serious about my photography while working on my PhD when I got funding from the National Geographic Society for field research. Through that connection, I was able to show them my pictures and eventually I published an article in the magazine about my work, which in turn meant I was able to get an assignment to document Cheryl’s orangutan PhD.

  • ‘Capitalism incarnate’: inside the secret world of McKinsey, the firm hooked on fossil fuels

    Interviews and analysis of court documents show how the world’s most prestigious consulting firm quietly helps fuel the climate crisis

    Two giant, mirrored walls are set to rise out of the sands of the Arabian desert. They will run parallel for more than 100 miles from the coast of the Red Sea through arid valleys and craggy mountains. Between them, a futuristic city which has no need for cars or roads will be powered completely by renewable energy.

    This engineering marvel, its creators say, will usher in “a revolution in civilization”. It’s the jewel in the crown of a $500bn Saudi government project known as Neom, turning a vast scrubland into a techno-utopia and world-class tourist and sporting destination. Perhaps a harbinger for the end of oil, it will supposedly put the powerful petrostate at the forefront of the energy transition. For American consulting giant McKinsey & Company, its advising on this project appears to be making good on the firm’s green promises.

  • Blackouts, explosions, deaths: why the Caribbean is waking up to the increased threat of lightning

    A recent strike narrowly missed slave trade archives in Barbados, and experts warn more and worse is to come as global heating intensifies storms

    When the Barbados National Archives, home to one of the world’s most significant collections of documents from the transatlantic slave trade, reported in June that it had been struck by lightning, it received widespread sympathy and offers of support locally and internationally.

    A section of the 60-year-old building, Block D, located on the grounds of the “Lazaretto” (the island’s former colony for people with leprosy), caught fire, and sustained serious damage. Official documents including hospital and school records were lost. “It was not just paper that was in the building, but documents that have stories about our families and ancestors,” says the chief archivist, Ingrid Thompson.

  • Plantwatch: Arctic microalgae perform photosynthesis in near darkness

    Unlocking secrets of how the algae survive could help extend growing seasons for crop plants at high latitudes

    Plants left for too long in the dark usually turn sickly yellow and die, but scientists were astonished to discover tiny microalgae in the Arctic Ocean down to 50 metres deep can perform photosynthesis in near darkness.

    The microalgae were at 88-degrees north and started photosynthesising in late March, only a few days after the long winter polar night came to an end at this latitude. The sun was barely poking up above the horizon and the sea was still covered in snow and ice, barely allowing any light to pass through. Typical light conditions outside on a clear day in Europe are more than 37,000-50,000 times the amount of light required by these Arctic microalgae.
