Late blight, inokonzerwa ne Phytophthora infestans, ndicho chirwere chakaipisisa chembatatisi pasi rose chinogona kukonzera kurasikirwa negoho rinosvika 100% pasi pemamiriro ezvirwere. Chidzidzo chezvino chakaitwa kuti chiongorore uye kuona chinoshanda trichoderma inozviparadzanisa nechirwere. Makumi matatu nepfumbamwe ega ega trichoderma spp. yakasarudzika kuNepal Plant Disease uye Agro Associates (NPDA), Kathmandu kubva kuLikhu nzvimbo dzeNuwakot, Nepal dzakaongororwa. P. infestans mune yakavharwa mashizha assay yekubudirira kwavo mukuderedza saizi yeronda rekunonoka blight. Zvikamu gumi neshanu zvakadzikisira zvakanyanya saizi yeronda ne19% -46% zvichienzaniswa nekutonga (mvura yekupfapfaidza). Pakati pavo, gumi epamusoro akazvitsaura pamwe chete neSanjeevni (T. viride), chigadzirwa chekutengesa chakaedzwa mukuedza kwemunda pasi pechisikigo epiphytotic mamiriro kuThansing uye Dhikure yeLikhu Rural Municipality muna 2020-2021 uye 2022-2023 makore ezvirimwa, zvichiteerana. The trichoderma inobata zvakanyanya (p <.001) yakawedzera kukura kwemiti, tuber goho uye kuderedza kuoma kwechirwere mumakore maviri. Muna 2020-2021, inotsaura, TL1-2A, TL4-81A uye TL5-21A yakaderedza kuomarara kwechirwere ne37.3%, 37.2% uye 30.4%, zvichiteerana. Iyo yega TL1-2A yakawedzera zvakare kureba kwechirimwa, kufukidzwa kwevhu uye goho retuber ne41.2%, 30.3% uye 72.3%, zvichiteerana zvichienzaniswa nekutonga (mvura yekupfapfaidza). Muna 2022–2023, TL1-2A yakaderedza kuomarara kwechirwere ne40.2% uye yakawedzera goho rechubhu ne46.4%. Zvimwe zvakaparadzana, kunyangwe zvakasiyana zvakanyanya kubva pakudzora, hazvina kuita zvinogutsa pakutonga kwechirwere uye goho rehubhu. Mumakore ese ari maviri, iyo yega TL1-2A yakaderedza zvakanyanya chirwere ichi, uye yakawedzera kukura kwechirimwa uye tuber goho.
Nekudaro, TL1-2A yekuzviparadzanisa nevamwe inogona kuve ingangoita mumiriri seye biocontrol mumiriri weiyo yakasanganiswa manejimendi yembatatisi yanonoka blight muNepal.
