Mtundu wa insecticidalDinotefuranndi yotakata, ndipo palibe kutsutsana ndi zomwe zimagwiritsidwa ntchito nthawi zambiri, ndipo imakhala ndi mayamwidwe abwino a mkati ndi ma conduction, ndipo zigawo zogwira mtima zimatha kutumizidwa ku gawo lililonse la minofu ya zomera. Makamaka, kulamulira kwa nsabwe za m'masamba, nsikidzi, obzala mpunga, thrips ndi tizilombo tina toluma kunali kothandiza kwambiri. Komanso, imathanso kukwaniritsa zolondola kwambiri zolepheretsa kuyamwa kwa tizirombo.
1. Mbewu zamasamba (pogwiritsa ntchito l % granules ndi 20% granules zosungunuka m'madzi) : l % granules akhoza kusakaniza ndi nthaka dzenje la dothi panthawi yobzala zipatso ndi ndiwo zamasamba ndi masamba a masamba, kapena kusakaniza dothi m'manja kufesa ngalande panthawi yofesa. Izi zimatha kuthana ndi tizirombo toyambitsa matenda panthawi yobzala komanso tizirombo touluka tisanasinthidwe. Komanso, chifukwa mankhwala ali wabwino mayamwidwe ndi conduction tingati mwamsanga odzipereka ndi zomera pambuyo mankhwala, ndipo akhoza kukhala lapamwamba kwa 4 mpaka 6 milungu.
20% ma granules osungunuka m'madzi atha kugwiritsidwa ntchito ngati mankhwala a tsinde ndi masamba pothana ndi tizirombo. Njira ziwiri zochiritsira, "mankhwala otsekemera" ndi "mankhwala osakaniza nthaka panthawi ya kukula", akuyesedwa. Ma granules omwe atchulidwa pamwambapa amatha kuphatikizidwa ndi ma granules osungunuka m'madzi kuti athe kugwiritsidwa ntchito kuyambira pachiyambi cha kukula kwa mbewu mpaka kukolola.
2. Mitengo yazipatso (20% granules zosungunuka m'madzi) : Ma granules osungunuka m'madzi amagwiritsidwa ntchito ngati mankhwala a tsinde ndi masamba pamene tizilombo toyambitsa matenda timapezeka, zomwe zimatha kuthetsa nsabwe za m'masamba, kuyamwa tizilombo tofiira, tizilombo toyambitsa matenda, ndi tizilombo toyambitsa matenda a lepidoptera. Kuphatikiza apo, ilinso ndi zotsatira zabwino zowononga tizirombo, komanso zimalepheretsa kuyamwa. Palibe vuto ku mbewu pamene mlingowo ukugwiritsidwa ntchito, ndipo mbewu zimachulukanso pamene mlingowo umawirikiza kawiri. Monga momwe zimagwiritsidwira ntchito pa mbewu zamasamba, zimakhala ndi zotsatira za kulowetsedwa ndi kusamuka kuchoka pa tsamba kupita ku tsamba mkati. Panthawi imodzimodziyo, pali adani achilengedwe ofunika kwambiri ku mitengo yazipatso.
3, Mpunga (2% mmera bokosi granules, l% granules, 0.5% DL ufa) : Pamene ntchito mpunga, DL ufa ndi granules angagwiritsidwe ntchito 30kg/hm2 mlingo (yogwira pophika 10 ~ 20g/hm2), amene angathe kulamulira bwino mphutsi za plantworms, nsonga zakuda, nsonga zakuda, nsonga zakuda tizirombo. Makamaka kwa tizirombo toyambitsa matenda, kusiyana kwa mphamvu ya mankhwala pakati pa mitundu ndi kochepa kwambiri. Ikagwiritsa ntchito bokosi la mbande, imatha kuwongolera bwino mbewu ya planthopper, nsonga ya mchira wakuda, bug ya mpunga ndi borer wamadzi wa mpunga pambuyo pa kumuika. Mankhwalawa amakhala ndi nthawi yayitali yotsalira pa tizirombo zomwe tikulimbana nazo, ndipo amatha kuwongolera kuchuluka kwa tizilombo pakadutsa masiku 45. Pakalipano, kuyesa kwina kukuchitika pa tizirombo monga Borer, borer ndi mpunga wakuda.
