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.

  • UK looking to give carmakers incentives to turn EVs into ‘power plants on wheels’

    V2G tech enables drivers to charge automatically when electricity is cheaper and then sell some back to the grid at times of high demand

    Electric cars that can be used as “power plants on wheels” could be given government backing as part of plans under consideration to help UK manufacturers.

    Ministers are considering giving manufacturers incentives to add “vehicle to grid” (V2G) technology to cars as part of its review of the zero-emission vehicle (ZEV) mandate.

  • Cabinet split emerges over controversial Rosebank oilfield decision

    Chancellor is in favour of North Sea project, but energy secretary has said she is leaning towards rejecting it

    A cabinet split has emerged over whether to approve drilling at the Rosebank oilfield, with the chancellor, John Healey, in favour of the controversial North Sea project.

    The energy secretary, Miatta Fahnbulleh, is ultimately in charge of the decision, and the Guardian reported last week that she was leaning towards rejecting it after granting permission for the smaller Jackdaw gasfield.

  • ‘They paved paradise’: fighting back over the loss of green spaces in Cameroon’s capital

    Concrete sprawl in Yaoundé has devastated the city’s trees and parks, so volunteers are stepping up, shrub by shrub

    A little piece of paradise is buried under the asphalt that is now lined with parked cars. The romantic spot where Sosthène Hugues Ngono used to bring his first dates had been green and beautiful. “It wasn’t just a park,” he says, standing at the edge of what is now a private car park in Cameroon’s capital, Yaoundé.

    “It was where I came to clear my head when things felt confused,” he says. “Where I met people; where I fell in love, more than once.”

  • Country diary: Jackdaws carve up the sky as dusk descends on the moors | Richard Smyth

    Eldwick Crag, West Yorkshire: In the low light and the high wind, these corvids are preparing to roost for the night. And they seem to be enjoying themselves

    Jackdaws like blustery weather the same way dolphins love choppy seas. There are faster flyers and more graceful flyers, but I can’t think of a bird that just enjoys flying as much as a jackdaw does. They bob and bank and yaw and wheel. And right now it’s roosting time in the copse above the quarry.

    A jackdaw roost – or rather the prelude to the roost, the bedtime gathering, the swirl of small, clacking crows above and about the trees, like particles about to be drawn into a plughole – isn’t a murmuration. It’s neither as spectacular nor as enigmatic as the twilight displays of starlings; it’s a flock, plain and simple (plain as the jackdaw’s call of its own name, “jack”). But like everything jackdaws do, it’s full of bustling, garrulous life.

  • Lights out: the island that goes dark to save young seabirds – in pictures

    Every autumn, Corvo Island in the Azores turns off its public lighting for a few key days to help fledgling Cory’s shearwaters as they attempt to fly to the ocean guided by the stars

    Once a year, Corvo, the smallest and most northerly island of Portugal’s Azores archipelago, goes dark. Since 2019, the island’s 450 or so inhabitants have chosen to switch off the lights every autumn for five nights to tackle the disastrous effects of artificial light on Cory’s shearwaters, a seabird endemic to the Atlantic Ocean.

    It began in 1991 when the community noticed huge numbers of deaths among young shearwaters.

  • U-turn on EV policy could stall UK’s take-up of EVs | Fiona Harvey and Jasper Jolly

    The 2030 target for 80% of new cars to have zero emissions could be cut to as low as half

    Electric cars make people happy. More than nine in 10 EV drivers – 94% in a recent poll – are saving money, and a similar number would stick with electric for their next purchase, and recommend them to family and friends. Sales are soaring: more than half of the new cars sold in the UK last month were electric, if hybrids are taken into account, and about 28% of new car sales overall were electric only.

    This is hardly surprising, given that soaring petrol and diesel costs have pushed up the price of a full tank to about £120. EV drivers are paying about 2.4p a mile.

  • ‘You need persistence’: the Norfolk couple who took on environmental regulators three times – and won

    Tim and Geli Harris have spent more than a decade fighting to protect Catfield Fen, a rare wetland in the Norfolk Broads

    Polluters and regulators who fail to stop pollution must quake in their boots when they receive a letter from the lawyers for Tim and Geli Harris. The couple, who farm 460 acres in the Norfolk Broads, have now scored a hat-trick of landmark legal victories to save an internationally important wetland after they won again in the high court this month.

    Lady Justice Lieven found that Natural England failed in its statutory duty to protect Catfield Fen from pollution after nitrates and phosphates washed from arable fields into one of the finest examples of calcareous fen in western Europe, home to 2,500 species including rarities such as the fen orchid, crested buckler fern, breeding bittern and swallowtail butterflies.

  • Sunlight at night: US startup’s demonstration of lighting Earth from space draws critcism

    Company imitates reflection of sun from mirrors, prompting pushback from some scientists, environmentalists and California locals

    Locals in a rural area of California were recently startled to see dazzlingly bright light shining down from nearby mountains at night, illuminating a swathe of the desert below.

    Unbeknown to them, the strange nocturnal illumination was the latest step in a company’s plan to erect thousands of giant mirrors in space to reflect sunlight on to the Earth during night-time.

  • Koalas are cute, furry, iconic – and dying of chlamydia. But how well does the approved vaccine work?

    Queensland researchers say a published study contains ‘silly mistake’ that over-inflates vaccine’s efficacy but the regulator is standing by decision to approve it

    At wildlife hospitals across eastern Australia, many koalas brought in have distinctive brown patches on their bottoms – a sign of urinary incontinence and a painful inflamed bladder. Others have red, weeping eyes, pointing to a bacterial disease that can cause blindness in the endangered marsupials.

    Chlamydia infection, also known as chlamydiosis, is the most significant disease affecting the animals. The culprit is most commonly the bacterium Chlamydia pecorum, which is spread via mating or close contact.

  • ‘Bolso shows all signs of fascism’: the journalist who predicted Brazil’s future – and paid the ultimate price

    Dom Phillips warned that Jair Bolsonaro would make life more dangerous for reporters and the Amazon rainforest, and that his sons were even more extreme

    “Bolso shows all signs of fascism, as do his supporters,” the murdered British journalist Dom Phillips told me before his death. “His sons are all more extreme if anything.”

    These words were written in 2018 by the Guardian contributor shortly before the election of the far-right former army captain Jair Bolsonaro as president of Brazil – a prospect that Dom viewed with dread.
