Momwe mungasamalire nkhaka kuchokera ku nsabwe za m'masamba: Njira ziwiri zotetezera zobzala
Mabedi a nkhaka amapezeka pafupifupi m'munda uliwonse. Masamba awa ndi amodzi mwa mbewu zodziwika bwino pakati pa anthu okhala m'chilimwe ndipo, monga ena, nthawi zambiri amadwala ndi tizilombo towononga. Mmodzi mwa alendo pafupipafupi komanso osasangalatsa pa nkhaka ndi nsabwe za m'masamba.

Zizindikiro za nsabwe za m'masamba pa nkhaka
Nsabwe za m'masamba yaying'ono kwambiri, koma nthawi yomweyo tizilombo towopsa. Atakhala m'munda wa nkhaka, amatha kulanda tchire zonse munthawi yaifupi kwambiri ndikuchulukitsa gulu lawo lankhondo ndi mazana angapo.
Tizilombo tambiri timadya kuyamwa kwa mbewu ndipo zitha kuvulaza nkhaka.
Kukhalapo kwa tizilombo m'munda kungasonyezedwe ndi zotsatirazi Zizindikiro:
- kusiya kukula ndi kufota kwa zipatso;
Nsabwe za m'masamba pa tsamba la nkhaka.
- mapindikidwe ndi kupindika kumtunda kwa mphukira zazing'ono;
- masamba ndi masamba amakutidwa ndi chinthu chomata;
- m'mphepete mwa pepala mbale amapindika pansi;
- kupanga zipatso kumachepetsedwa kwambiri;
- tchire louma ndikuwoneka lopweteka;
- nyerere zambiri zimawonekera pa tsinde la chomeracho komanso pafupi ndi mabedi.
Momwe mungachotsere nsabwe za m'masamba pa nkhaka
Mutha kulimbana ndi nsabwe za m'masamba pamabedi a nkhaka, komanso pamitundu ina ya zomera, mothandizidwa ndi mankhwala owerengeka ndi mankhwala.
Mankhwala
Mankhwala ophera tizilombo amakhala ndi zinthu zapoizoni choncho amagwiritsidwa ntchito pokhapokha pakagwa mwadzidzidzi, pamene chiwerengero cha tizilombo towononga chawonjezeka kwambiri.
Kuphatikiza apo, mankhwalawa amaletsedwa kugwiritsa ntchito nthawi ya fruiting, apo ayi mbewuyo idzakhala yosayenera kumwa.
Kwambiri mankhwala ophera tizilombo kwa processing nkhaka ndi:
- Muvi;
- Fitoverm;
- Entobacterin;
- Fufanon;
- Mtsogoleri;
- Spark.
Njira za anthu
A kwambiri okhulupirika njira kuwononga tizirombo pa nkhaka ndi maphikidwe achikhalidwe. Wamaluwa ambiri amakonda kulima mabedi ndi njira zotere, chifukwa ndi abwino ku zipatso zonse komanso tizilombo topindulitsa tomwe timatulutsa mungu.
Black aphid pa nkhaka.
Zotsatirazi ndizoyenera kwambiri pokonza nkhaka:
- viniga njira;
- yankho la sopo ndi phulusa la nkhuni;
- chisakanizo cha madzi, ayodini ndi mkaka;
- soda yothetsera.
Lumikizani mutha kusankha kuchokera ku njira 26 zogwira mtima za aphid.
Kupewa maonekedwe a nsabwe za m'masamba pa nkhaka
Kuti musasokoneze ndi mlendo wosasangalatsa pamabedi, chisamaliro choyenera chiyenera kuperekedwa popewa. Kukhazikitsa pafupipafupi malangizo awa kudzathandiza kupewa kuoneka kwa tizilombo:
- kuyeretsa nthawi yake mabedi ku zinyalala za zomera ndi udzu;
- kukumba pachaka kwa dziko lapansi m'mabedi m'dzinja;
- kudula udzu pa nthawi yake;
- kulimbana ndi nyerere;
- kuyeretsa kuchokera pamalo a matabwa, zitsa ndi zomangira.

Pomaliza
Maonekedwe a tizilombo totere monga nsabwe za m'masamba pamalowa amafunika kuchitapo kanthu mwachangu kuchokera kwa wolima dimba. Tizilombo tating'onoting'ono timachulukana kwambiri ndipo timawononga kwambiri mbewu. Kuteteza zomera ku nsabwe za m'masamba ndi tizirombo tina toopsa, njira zodzitetezera nthawi zonse komanso chithandizo chanthawi yake pamene zizindikiro zoyamba za kuwonongeka zingathandize.
