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.

  • Rail services, schools and sports events hit, with deaths of three elderly people in France partly blamed on intense heat

    Western Europe is enduring a ferocious heatwave forecast to break temperature records, with half of France on red alert, rail services in Belgium disrupted and sports events in Spain and Germany cancelled or postponed.

    French authorities on Monday placed 49 of the country’s 96 mainland departments on a level 1 danger-to-life warning, urging 35 million people to exercise “absolute vigilance”, drink water often, avoid all strenuous exertion and stay out of direct sun.

  • UN’s World Food Programme and agriculture agency issue joint appeal for funds to avert global hunger crisis before it happens

    Adugna Woyessa was a little boy the first time drought tore his country apart. As harvests failed in rain-starved regions of Ethiopia in the early 1970s, and his school turned a classroom into a grain store for farmers to send aid, he had no idea that scientists were beginning to connect the force parching its fields with cyclical shifts in trade winds that had long supercharged violent weather from South America to Australia.

    The now notorious El Niño – Spanish for “little boy” was named by fishers in the Pacific in the 1800s, but it was not until the 1970s that scientists understood its global nature and began to piece together the historical impact of the natural weather pattern characterised by hot years and brutal extremes.

  • Abernethy forest, Cairngorms: One of my favourite species, the tiny twinflower, does better in Scots pinewoods than most places in the UK. Now I just have to find some

    The soundtrack to my day is the calls of siskins, blackcaps, willow warblers, coal tits and tree pipits, the drumming of a great spotted woodpecker and an occasional cuckoo. But this morning my gaze is aimed downwards. I’m walking slowly, gingerly, looking for a colony of twinflowers that I know I’ve seen around here before.

    They’re one of my favourite flowers and a sign for me that summer is here. Standing just 10cm in height, their stems form a delicate Y with two, tiny, beautiful pale pinkish-white bell‑shaped flowers that hang from each of the tops.

  • Smaller, cheaper cars built for narrow city streets are becoming more stylish – but require careful design decisions

    The winding backstreets of London, Paris and Rome are a large part of their charm. But they are also a problem for electric carmakers. For a long time, squeezing big batteries into smaller, cheaper cars to fit European streets was too much of a problem, so manufacturers focused on bloated SUVs instead.

    But that is finally changing. Battery technology has improved and Europe’s carmakers havecut manufacturing costs enough that they can now sell cars that might have a chance of fitting down a medieval lane or two.

  • Exclusive: European Commission planning to rewrite key law to allow water-intensive mines in regions suffering from drought

    The European Commission plans to rewrite the EU’s flagship water protection law to speed up the development of critical minerals mines, despite many being located in drying and water-stressed regions, analysis has found.

    Mining is a water-intensive industry, requiring large volumes of water for ore processing, dust suppression, waste management and mine dewatering. While modern projects recycle water, they still require significant amounts, and in water-stressed regions those demands can add to pressure on already stretched rivers, aquifers and water supplies.

  • The reconstruction of the vaquita, whose numbers barely reach double figures in the wild, is designed to help research and conservation efforts

    Scientists have created a digital reconstruction of the world’s most endangered marine mammal, preserving its anatomy in three dimensions to aid research and conservation efforts as the species teeters on the brink of extinction.

    The project digitised the skeleton of a female vaquita, a small porpoise found only in Mexico’s northern Gulf of California, using a combination of medical imaging, ultra-high-resolution micro CT scans and photography.

  • Blaenau Ffestiniog, Gwynedd: This living sculpture, planted in the 1970s ‘for the 21st century’, is fading fast. But heartbreak is not the only response

    Ten years ago when I visited the Ash Dome, it was an elegant, twisting circle of beautiful trees. Ten years ago, ash dieback had not yet reached this corner of Wales. Returning now to this secret location, I steeled myself for heartbreak. And there it was.

    Today, the Ash Dome, a living sculpture by the renowned artist David Nash, is an elephant’s graveyard. Pale, twisted limbs encircle a heap of dead branches. On a few trunks, new shoots spring innocently upwards, but most are ailing, their bark white and flaky as dead skin.

  • A national heatwave plan has been activated to help people stay cool during the Netherlands’ increasingly hot summers

    Households in Amsterdam are being urged to hang their curtains outside their windows as health experts recommend simple hacks to moderate the heatwave rolling across the Netherlands, where homes were built for old-fashioned damp and coldish northern European weather.

    In a viral social media post last week, Eline Coolen, the heat coordinator at the city’s public health institute, urged sweaty city-dwellers to rig up temporary curtain rails or drape curtains or sheets outside to stop the sun’s rays reaching their large windows.

  • Forced to stay home or switch jobs, working mothers are bearing the brunt of the climate crisis as classes go online for weeks or months at a time

    Outside, the temperature has passed 41C (105.8F). Inside Sakshi Katyal’s city apartment, the air conditioner is blasting but it does little to relieve the stress of balancing housework and helping her five-year-old log in on a laptop to online classes. Her daughter’s school closed in May and Katyal is not clear when it will reopen. Probably not till the autumn.

    Schools across Delhi and in about half of India’s 28 states have been ordered to close from mid-May until the end of June, when in many places the summer break starts. There is no official record of closures in past years but the Guardian has spoken to school officials who say the number of days schools are shut for because of the heat has risen sharply. The impact on families, especially on working women, has been huge.

  • Opposition to plans for ‘small paradise’ island of Sazan becomes wave of dissent against establishment

    For Ina Shkurti, like so many Albanians, the island of Sazan has played an outsized role. As a child she bathed in its “always calm and emerald green” waters, as a teenager it figured in her dreams and as an adult it was an indelible part of the memory and desire that drew her back, every summer, to Vlore, her home town across the sea.

    What Shkurti never imagined was that plans to build a mega-resort on Sazan – one of two luxurious complexes on Albania’s southern coast backed by Ivanka Trump and her husband, Jared Kushner – would trigger a revolt, an uprising that has convulsed the Balkan state in a spasm of disgust over the perceived excesses of “a rotten oligarchic class” just as it hopes to complete accession talks with the EU.
