Masana abwino, owerenga anga. Rapiberi ya raspberries sakhala azomera zowopsa. Komabe, kutalika kwa nyengo, zipatsozo zimayamba kufa ndi kugwa. Zimafunikira kudziwa zomwe zimayambitsa vutoli ndikuchotsa, apo ayi mutha kukhala popanda mbewu komanso nyengo yotsatira.
Zifukwa zodziwikiratu
- Umuna wokwanira (kusala kwa nayitrogeni);
- kuthirira kosakwanira;
- Kumasulidwa kwakukulu kwa dothi lomwe mizu yawonongeka.
Momwe Mungapangire Zolakwika
- Pezani mbande zapamwamba;
- Dulani tchire;
- perekani kuthirira, kupanga feteleza;

Ma virus chlorosis
Ndi zowonongeka kwa chlorosis, njira zamapangidwe a chlorophyll amasokonezeka, zomwe zimayambitsa kuchepa kwa photosynthesis.
Ngati chlorosis si chilengedwe, ndiye chifukwa chakupha masamba kumapeto kwa zinthu kapena nyengo yoipa. Ndi kachilomboka kachilomboka, mbewu zimakhudzidwa ndi rasipiberi mitsempha ya chlorosis virus.
Zosefera masamba zimaphatikizapo zipatso zotopa ndi kufa. Chifukwa chokwanira photosynthesis, zipatso sizimapeza chinyezi komanso michere komanso yabwino.
Zizindikiro
Ogawa a chlorosis tll ndi nkhupakupa. Mutha kupatsira chomera popatsidwa katemera wodwala kapena kugwiritsa ntchito chida chomwe chadwala. Vutoli lili ndi madzi azomwe zakhudzidwa.
Momwe mungagonjere matenda a chlorosis sikiloli, kenako kupulumutsa mbewuzo zitha kupangidwa ndi feteleza wofunikira m'nthaka, pogwiritsa ntchito mitundu yopanda mizu komanso nthambi.
Pankhani ya chlorosi ya chlorosis, mbewu ziyenera kuwononga.
Kulepheretsa
Kupewa kumachitika motsutsana ndi nkhupakupa ndi tinthu. Kuponyera mankhwala "Fufunon Nova", "Va-VIRA", ndi zina zambiri.
Kupewa kumatha kuonedwa kuti kuli mitundu yolimbana ndi chlorose, kukolola kwa Russia, Viownish Victoria.
Khalani osakolola zipatso zotsekemera komanso zonunkhira zimanyoza mlimi aliyense. Tiye tikambirane za nkhondoyi komanso kupewa raspiberi matenda opatsirana.
Mosic
Mossic ndiye dzina lonse la matenda omwe amayambitsa mawonekedwe a masamba. Zomera zomwe zakhudzidwa zimafota, mphukira zimakokedwa, ndipo zipatso zimakhala zazing'ono kapena zowuma.Mafunde onse ndi zimbudzi zonse amasamutsidwa, ndipo imagwera mu zomera chifukwa chowonongeka kutumphuka.
Masamba a sypoptomy m'dera lokhalamo limawoneka ngati mawanga owoneka bwino komanso achikasu amdima, omwe pakapita nthawi amayamba kupanga pamwamba pa pepalalo. Amasima wowonda komanso wowuma.
Momwe mungagonjere matenda owononga.
Kudzitchinjiriza kukonza kuchokera kwa tery ndi mutu. Ndikuchotsa mbande zathanzi. Kukonza ndi kukonzekera kwa "pentafag" masiku 8-12.
Vertillillome
Kutenga kachilomboka komwe kumakhala m'nthaka kumakhudzanso mphukira zazing'ono ndi mbewu zowonongeka mizu. Mafangayi amagwira ntchito kwambiri ngati nyengoyo inali yonyowa, ndi masiku otentha komanso usiku wozizira.
Chizindikiro cha pakati pa chilimwe, masamba amayamba kutembenukira chikasu ndikuwonongeka, woyamba akuvutika. Masamba ndi achikasu ochokera m'mphepete mpaka pakati, ming'alu imawonekera pa cortex, zipatso zimawuma.
Momwe mungathane ndi matenda opatsirana ndi mbewu zathanzi, osagwiritsa ntchito mundawo, komwe matenda ali ndi verticillosis amawonedwa.
Kuona
Matenda. Matenda amabwera kuchokera ku tw ndi nkhupakupa, komanso zomera ndi zida.
Ma Sypops amakhumudwa ndikufupikitsa, masamba amakhala ocheperako komanso opotoka. Zipatso zimawuma ndikugwa, ndipo kusungidwa kumakhala komwala.
Momwe mungathane ndi matenda omwe ali ndi matenda amkatiwo amafa mosachedwa zaka 2-4. Adawotchedwa. Pofuna kupewa mbewuyo, amathandizidwa kuchokera ku Tsley ndi manenedwe ndi mankhwala osokoneza bongo ", chisoni", "chisoni", "fufanon-Nova".
