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.

  • Major incident declared, with Sizewell B power station monitoring blaze and RSPB nature reserve badly hit

    Hundreds of people have been evacuated and a major incident declared after a wildfire spread over more than 80 hectares (200 acres) on the coast of Suffolk, just a few miles from the Sizewell B nuclear power station.

    The fire – which had been described by one witness as “apocalyptic” – was said to be stabilising on Thursday night. The statement was posted by Suffolk Fire and Rescue Service, which said at least 12 fire crews were remaining overnight in the area.

  • Ferocious flames continue to rage in parts of France and Spain, with no sign of abating. We chart the destruction in graphics and pictures

    The hellish infernos that have torn through parts of France and Spain have caused deaths, the evacuation of 330,000 people from their homes, widespread destruction and clouds of toxic smoke. Records have already been smashed and with the fourth heatwave of the European summer setting in, there are few signs of the waves of wildfires ending.

    France has already surpassed the worst previous year for the size of the area burned, with August, usually the hottest month, yet to come.

  • Forty hectares of Oaken Wood could be razed after it was identified as potential site of expansion by Reform-run council

    It was at the confluence of seven forest paths that Allison Sweetman came to a stop. Trees rose on all sides, save for a recently coppiced section to the north-east. The noon heat had silenced most birds, but the quiet was peaceful.

    “This is what they call Seven Wents,” she said. For centuries, the people of Kent had travelled this way, from East Malling to Barming, from Ditton to Teston, for church, commerce and friends. “It’s on maps going back 400 years.”

  • Analysis of samples collected from carcasses found traces of toxic chemical compound, says Kenya Wildlife Service

    The recent deaths of 15 elephants near a park in southern Kenya in the past month were likely caused by the animals ingesting pesticides used on nearby tomato farms, the Kenya Wildlife Service (KWS) has said.

    Erustus Kanga, the agency’s director general, told Citizen TV that analysis of samples collected from the carcasses had found traces of cyanide, a chemical compound used in farming as a predator control poison and a pest fumigant, which has also been used by poachers.

  • From Leicestershire to Carmarthenshire, neighbourhoods are struggling with wave after wave of houseflies. Why are they suffering while others are spared? And is there no alternative to nets and zappers?

    Francesca Davies’s living room is absolutely teeming with flies. You can’t enter the contact centre worker’s home without a cluster of insects rising from the sofa or the floor to buzz around your face. Davies and her family live in West Heath, a suburb of the Cheshire town Congleton. Davies’s husband, Alex Andrew, a 29-year-old maintenance engineer, grew up in the market town and he used to think of West Heath as a desirable area, with its well-maintained houses and access to green space. When he and Davies were able to buy a new-build here in 2019 via a shared ownership scheme, they felt incredibly lucky. That is, until they moved in, and realised that every summer swarms of flies descend on their neighbourhood, an issue that is “getting worse”, Davies says.

    At the moment, the 27-year-old swats flies out of her young daughters’ bedroom every night before she puts them to bed, and keeps doors and windows closed or covered with fly nets as much as possible. She and Andrew have even bought an industrial fly killer (like the ones often found in fish and chip shops) for their kitchen, as it is impossible to start cooking without attracting even more insects. The pair have become used to the sound of flies “getting zapped throughout the night”, Davies says.

  • Boom in migrating moth sightings put down to hot weather, strong winds and food scarcity in Europe

    He had just sat down to dinner in the garden when a speedy visitor whizzed by – a “grey lump with orange wings”, recalled Luke Burstow, from Sussex. It was a hummingbird hawk-moth, a flying insect that migrates to the UK from continental Europe and north Africa.

    “I was like: ‘Wow!’,” said the software project manager. “I didn’t even know they existed.”

  • Liverpool: Paul McCartney’s latest album has brought tourists here, but there’s so much more to see than the sign

    Earlier this year, Paul McCartney released an album called The Boys of Dungeon Lane. Among the unashamed nostalgia is a wistful track, Days We Left Behind, which evokes memories of his visits to the Mersey shore with George Harrison and friends. Young Paul was, it turns out, a keen birdwatcher.

    Perhaps inevitably, the album has brought crowds of tourists to photograph the sign. The Speke end of the lane where they mostly gather is uninspiring, bounded by remnants of a demolished pub, a solar farm and an electricity substation.

  • Several councils to stop housing tenants in glass-fronted Britannia Point in London, where tenants were earlier told they could not use air con

    As the fourth heatwave of the year hit the UK on Wednesday, Benice Bodah and her three teenage sons braced for more scorching temperatures inside their south-west London home. The two-bedroom flat has a built-in air-conditioning unit, but it has worked only intermittently in the almost three years since the family were placed in temporary accommodation at Britannia Point in Colliers Wood. “It has not been easy, but what can we do?” said Bodah, 48.

    Several councils have now agreed to stop housing families in emergency accommodation in the glass-fronted block after the Guardian revealed they had been told they couldn’t use the air-conditioning during heatwaves as it had “not been offered as an amenity” for them. The 19-storey building is owned by Criterion Capital, set up by the billionaire property magnate Asif Aziz. The temporary tenancies can last from weeks to years and are managed separately by letting agencies, including the London-based Aura Assets Management.

  • Wild Inside looks back on the incredible year when an escaped zoo owl managed to bring New Yorkers together

    Flaco the Eurasian eagle-owl gained a cult following after leaving his life in captivity at the Central Park zoo in 2023 and surviving, against all odds, for more than a year as a free bird in Manhattan.

    Birdwatchers tracked his every move, capturing his vast wingspan and luminous orange eyes with their cameras. His fans got tattoos in his honor. And now, Wild Inside, a new documentary chronicling Flaco’s year about town, is set to premiere this week.

  • Preaktivan imunološki odgovor u mozgu može igrati ulogu u Dravetovom sindromu, rijetkoj i teškoj genetskoj epilepsiji koja obično počinje u djetinjstvu, prema znanstvenicima s Weill Cornell Medicine. Djeca s ovim stanjem imaju česte napadaje koje je često teško kontrolirati lijekovima, a mogu se suočiti i s razvojnim, kognitivnim i bihevioralnim izazovima. Do sada se većina istraživanja usredotočila na to kako mutacija u genu SCN1A remeti električnu signalizaciju u mozgu.

  • Nedavna studija otkrila je da parodontitis reprogramira neutrofile koštane srži putem metaboličkog puta glutationa pokretanog Chac2, potičući visoko upalno N1 stanje koje potiče sistemsku upalu.

  • Nedavni objavljeni pregled ispitao je dokaze o učincima borovnica, grožđa i njihovih bioaktivnih spojeva na markere kardiovaskularnog rizika. Bobičasto voće i grožđe sadrže širok raspon polifenolnih bioaktivnih spojeva, uključujući resveratrol, flavonoide i antocijanine, s protuupalnim, antioksidativnim i potencijalno kardioprotektivnim biološkim učincima.

  • Biljna prehrana potiče zdravlje crijeva, imunološkog sustava, metabolizma i kardiovaskularnog sustava, dijelom kultiviranjem raznolike zajednice crijevnih bakterija. Odavno je poznato da te koristi djelomično proizlaze iz vlakana u biljnoj hrani, koju prerađuju naše komenzalne crijevne bakterije, i često jarko obojenih fitokemikalija koje biljke proizvode kako bi se zaštitile od prijetnji iz okoliša

  • Američki znanstvenici s Kennedy Krieger Instituta i Johns Hopkins Medicine otkrili su da konsolidacija pamćenja tijekom spavanja ovisi o koordiniranoj aktivnosti između tri regije mozga, a poremećaji u toj aktivnosti mogu narušiti performanse pamćenja. 

  • Studija koju je provela Cleveland Clinic pokazuje vezu između povišenih razina TMAO-a (trimetilamin N-oksida) u krvi - nusprodukta probave hranjivih tvari koje se nalaze u crvenom mesu i drugim životinjskim proizvodima - i većeg rizika od fibrilacije atrija. Naime, pokazalo se, da TMAO koji proizvode crijevni mikrobi mijenja električno okruženje srca, povećavajući osjetljivost na abnormalne ritmove.

  • Prema rezultatima novog istraživanja, izgleda da je mikroglija primarni pokretač gubitka sna kod Alzheimerove bolesti. Korištenjem lijeka za privremeno uklanjanje tih stanica u životinjskim modelima, znanstvenici su uspješno obnovili više od dva sata sna dnevno, pružajući novu metu za liječenje bolesti.

  • Djeca hospitalizirana s teškom upalom pluća mogu sigurno prijeći s injekcijskih na oralne antibiotike nakon što se počnu oporavljati, što mnogima omogućuje brži povratak kući i završetak liječenja izvan bolnice, pokazuje nova studija.

  • Primarni bilijarni kolangitis rijetka je autoimuna bolest koja utječe na jetru i može napredovati u cirozu. Nastaje kada imunološki sustav napadne male žučne kanale unutar jetre. Kao rezultat toga, žuč se nakuplja, što dovodi do upale i progresivnog oštećenja jetre. Iako postoji terapija prve linije, 40% pacijenata ne reagira adekvatno na nju ili je ne može tolerirati, pa je potrebno razviti nove mogućnosti liječenja.

  • Od staničnog recikliranja do kognitivnog starenja, spermidin privlači znanstveni interes, ali dokazi potrebni za rutinsku ljudsku upotrebu još se pojavljuju. Spermidin je sveprisutni prirodni poliamin i mimetik kalorijske restrikcije, neophodan za staničnu proliferaciju i homeostazu tkiva.
