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.

  • Downing Street forces Tony Blair to row back from net zero strategy criticism

    Labour politicians warn former PM had boosted Tory and Reform climate sceptics on the eve of local elections

    Tony Blair has been forced by Downing Street to row back from his criticism of the government’s net zero strategy after furious Labour politicians warned he had given a boost to Tory and Reform sceptics on the eve of the local elections.

    Climate experts also accused the former prime minister of granting political cover to fossil fuel interests and weakening momentum behind the UK’s legally binding target to reach net zero emissions by 2050.

  • Nature nurture: the Devon estate where rewilding and mental health go hand in hand

    A restoration project at Sharpham near Totnes aims to tackle the loss of the natural world while helping people build mental resilience

    Two landscapes separated by a wide sweep of river tell a story of change. On one side is traditional farmland, close-cropped grazing, uniform grasses, neatly tended hedges and a sparsity of trees, a farmscape ubiquitous across England. On the riverbank opposite, rougher, less uniform grasses grow unevenly between trees, thistle and brambles, in a chaos of natural disorder swaying in the breeze towards the reedbeds below.

    The land on the Sharpham estate side of the River Dart used to be a mirror of the traditional farmscape on the opposite bank. It hosted a non-organic dairy farm and a vineyard, within a tightly controlled 18th-century heritage landscape of deforested parkland.

  • Attenborough at 99: naturalist ‘goes further than before’ to speak out against industrial fishing in new film

    The celebrated presenter warns of ‘modern day colonialism at sea’ as he highlights the destruction caused by overfishing and bottom trawling

    When David Attenborough’s Blue Planet II documentary aired eight years ago, its impact was so strong it was credited with bringing about a revolution in the way people use plastics. Now film-makers are hoping he can do the same for other destructive environmental practices that the world’s best-known living naturalist describes as “draining the life from our oceans”.

    The industrial fishing method of bottom trawling is the focus of a large part of Attenborough’s latest film, Ocean, which airs in cinemas from 8 May, the naturalist’s 99th birthday. In a remarkably no-holds-barred narrative, he says these vessels tear the seabed with such force “the trails of destruction can be seen from space”. He also condemns what he calls “modern day colonialism at sea”, where huge trawlers, operating off the coasts of countries reliant on fish for food and livelihoods, are blamed for dwindling local catches.

  • Arctic plant study reveals an ‘early warning sign’ of climate change upheaval

    A warming tundra has seen unexpected shifts, raising the alarm about fragile ecosystems and those who rely on them

    Scientists studying Arctic plants say the ecosystems that host life in some of the most inhospitable reaches of the planet are changing in unexpected ways in an “early warning sign” for a region upended by climate change.

    In four decades, 54 researchers tracked more than 2,000 plant communities across 45 sites from the Canadian high Arctic to Alaska and Scandinavia. They discovered dramatic shifts in temperatures and growing seasons produced no clear winners or losers. Some regions witnessed large increases in shrubs and grasses and declines in flowering plants – which struggle to grow under the shade created by taller plants.

  • Dying satellites can drive climate change and ozone depletion, study finds

    Aluminium emissions from satellites as they fall to Earth and burn up is becoming more significant as their numbers soar

    Right now there are more than 9,000 satellites circumnavigating overhead, keeping track of weather, facilitating communications, aiding navigation and monitoring the Earth. By 2040, there could be more than 60,000. A new study shows that the emissions from expired satellites, as they fall to Earth and burn up, will be significant in future years, with implications for ozone hole recovery and climate.

    Satellites need to be replaced after about five years. Most old satellites are disposed of by reducing their altitude and letting them burn up as they fall, releasing pollution into Earth’s atmosphere such as aerosolised aluminium. To understand the impact of these growing emissions from expired satellites, researchers simulated the effects associated with an annual release of 10,000 tonnes of aluminium oxide by 2040 (the amount estimated to be released from disposal of 3,000 satellites a year, assuming a fleet of 60,000 satellites).

  • ‘Chipmunks were obsessed with my mics’: the man who recorded a tree for a year

    Joshua Bonnetta spent 8,760 hours recording a pine – then honed it down into a four-hour album full of creatures, cracking branches and quite possibly the sound of leaves growing

    What does a landscape sound like when it’s not being listened to? This philosophical question was a catalyst for film-maker and artist Joshua Bonnetta, who has distilled a year of recordings from a single tree in upstate New York – that’s 8,760 hours – into a four-hour album, The Pines. As Robert Macfarlane writes in his accompanying essay, The Pines is a reminder of the natural world’s “sheer, miraculous busyness”, its “froth of signals and noise”. It is rich with poetic meaning, and resonant amid the climate emergency.

    “It started as a personal thing,” Bonnetta explains from his studio in Munich, where he relocated from the US in 2022. For over 20 years he has made sonic records of places as private mementos, but recent experiments with long-form field recording led him to push himself “to document this place in the deepest way I could”. On a residency in the Outer Hebrides between 2017 and 2019, Bonnetta made the sound installation Brackish, a month-long continuous radio broadcast from a weather-resistant hydrophone – an underwater mic – by a loch. “I started to leave the recorder for a day or two, then it just got longer,” he says. “Amazing things happen when you’re not there to interfere … This allows you a different, very privileged window into the space.”

  • Why effects of Michigan’s ice storm will linger for months, perhaps years

    Climate experts say warming atmosphere from climate change could fuel severe freezing rain and ice storms like the one that hit the upper midwest last month

    Winter has been slow to release its icy grip from the upper midwest this year, and in northern Michigan, its effects will be keenly felt for months, perhaps years.

    A devastating ice storm that hit late last month has left an estimated 3m acres of trees snapped in half or damaged from the weight of up to an inch-and-a-half of ice across the northern part of lower Michigan.
