Chinyorwa chino chakaongororwa zvichienderana nemaitiro eScience X ekunyora uye mitemo. Vanyori vakasimbisa zvinhu zvinotevera uku vachiona kuti zvirimo ndezvechokwadi:
Ongororo yakaitwa munguva pfupi yapfuura nevaongorori veOhio State University yakaratidza hukama hwakaoma pakati pevanodzora kukura kwezvirimwa uye kuramba kwehuswa hunokambaira huchirwisa matambudziko akasiyana-siyana ezvakatipoteredza, akadai sekumanikidzwa kwekupisa nemunyu.
Huswa hunokambaira (Agrostis stolonifera L.) imhando yehuswa hunoshandiswa zvakanyanya uye hunobatsira mune zvemari hunoshandiswa zvakanyanya munhandare dzegorofu muUnited States yese. Mumunda, zvirimwa zvinowanzosangana nematambudziko akawanda panguva imwe chete, uye kudzidza kwakazvimirira nezvematambudziko kungasave kwakakwana. Kushushikana kwakadai sekushushikana kwekupisa uye kushushikana kwemunyu kunogona kukanganisa huwandu hwe phytohormone, izvo zvinogona kukanganisa kugona kwemuti kutsungirira kushushikana.
Masayendisiti akaita ongororo dzakasiyana-siyana kuti vaone kana huwandu hwekumanikidzwa kwekupisa uye kumanikidzwa kwemunyu zvinogona kukanganisa hutano hwehuswa hunokambaira, uye kuti vaongorore kana kushandiswa kwezvinodzora kukura kwezvirimwa kunogona kuvandudza hutano hwezvirimwa pasi pekumanikidzwa. Vakaona kuti mamwe magadzirirwo ekukura kwezvirimwa anogona kuvandudza kushivirira kushushikana kwehuswa hunokambaira, kunyanya pasi pekumanikidzwa kwekupisa nemunyu. Izvi zvinopa mikana yekugadzira nzira itsva dzekuderedza migumisiro yakaipa yezvinodzvinyirira zvakatipoteredza pahutano hwevhu.
Kushandiswa kwezvinodzora kukura kwezvirimwa zvinoita kuti zvikwanisike kuwedzera kukura nekukura kwehuswa hunokambaira hune bentgrass kunyangwe paine zvinhu zvinonetsa. Kuwanikwa uku kune vimbiso huru yekuvandudza huswa hwakanaka uye kuchengetedzeka mumamiriro akasiyana-siyana ezvakatipoteredza.
Chidzidzo ichi chinoratidza hukama huripo pakati pevanodzora kukura kwezvirimwa nevanokonzera kushushikana kwezvakatipoteredza, zvichiratidza kuoma kwemaitiro ehuswa hwevhu uye kugona kwenzira dzekutarisira dzakagadzirwa. Tsvagiridzo iyi inopawo ruzivo runoshanda runogona kubatsira zvakananga vatariri vehuswa hwevhu, nyanzvi dzezvekurima, uye vane chekuita nezvakatipoteredza.
Sekureva kwemumwe munyori Arlie Drake, mubatsiri wepurofesa wezvekurima paClark State University, "Pazvinhu zvese zvatinoisa pamunda wehuswa, ndagara ndichifunga kuti zvinodzora kukura zvakanaka, kunyanya zvinodzivisa kugadzirwa kweHA. Zvikuru nekuti zvine mabasa, kwete kungodzora kukura kwakamira."
Munyori wekupedzisira, David Gardner, ipurofesa wesainzi yehuswa paOhio State University. Inonyanya kushanda pakurwisa sora mumasango nezvishongo, pamwe nepfungwa dzekushushikana dzakadai semumvuri kana kupisa.

Kana mukasangana nezvikanganiso zvisirizvo, kusarongeka, kana kuti muchida kutumira chikumbiro chekugadzirisa zviri papeji rino, ndapota shandisai fomu iri. Kana muine mibvunzo yakawanda, ndapota shandisai fomu redu rekutaurirana. Kuti muwane mhinduro dzakawanda, shandisai chikamu chemashoko everuzhinji chiri pazasi (teverai gwara).
Mhinduro dzenyu dzakakosha zvikuru kwatiri. Zvisinei, nekuda kwekuwanda kwemashoko, hatigone kuvimbisa mhinduro yakanangana nesu.
