Matenda a fungal m'maluwa a orchid amachokera ku zodzoladzola zokha zomwe zingawonongeke. Mwamwayi, pali mankhwala omwe amapezeka kuti athetse matenda ambiri a fungali .
Izi ziyenera kunenedwa, komabe kuti kulakwitsa kwakukulu kwa matenda a fungula m'maluwa a orchid ndiko kuteteza bwino. Khalani ndi chikhalidwe chabwino cha amaluwa ndipo mungathe kupewa nthawi yambiri ya matendawa. Komanso, zambiri zazing'ono za fungal, monga zazing'ono zakuda masamba, zimatha kulekerera popanda kugwiritsa ntchito mankhwala.
Pomaliza, ngati mutagwiritsa ntchito mankhwala, kumbukirani kuti nthawi zonse mumatsata malangizo.
Njira Zothandizira
Mndandanda wotsatirawu umaphatikizapo matenda omwe amapezeka ndi fungal ndipo amalimbikitsa organic ndi tizilombo kulamulira mankhwala:
- Matenda a anthracnose, Phytophthora, Botrytis, mildew, tsamba lakuda , ndi tsamba la masamba amatha kusungunuka soda osakaniza 4 Tsp / gal. Onjezerani 2 tsp./gal ya mafuta oyeretsedwa a horticultural kapena sopo la tizilombo. Limbikitsani milungu iwiri iliyonse. Ngati izi sizigwira ntchito, yesani mkuwa fungicide.
- Zowola zowonongeka ndi pseudobulb zowola zimatha kulamulidwa ndi mabakiteriya opindulitsa Streptomyces griseoviridis. Izi zimagulitsidwa malonda monga Mycostop, BioYield, Companion, ndi zina.
- Mankhwalawa amawoneka ndi BT (Bacillus thruingiensis israelensis), yomwe imapha ntchentche . Fufuzani Gnatrol.
- Botrytis, tsamba-spotting, ndi algae za masamba (zomwe zingayambitse matenda oopsa) zingathe kulamulidwa ndi dimethyl ndi ethyl benzyl ammonium. Funa Physan 20 kapena Greenshield. Ambiri odziŵa ntchito amagwiritsa ntchito mankhwalawa monga mankhwala opopera. Yesetsani masiku asanu ndi awiri kapena 10 aliwonse, osankhidwa kuti akhale gawo limodzi kapena theka la mphamvu zopangira mankhwala.
