Momwe Mungagwiritsire Ntchito Dinotefuran

Mitundu ya mankhwala ophera tizilomboDinotefuranNdi yotakata pang'ono, ndipo palibe kukana kwa zinthu zomwe zimagwiritsidwa ntchito nthawi zambiri, ndipo imakhala ndi mphamvu yabwino yoyamwa ndi kuyendetsa bwino mkati, ndipo zigawo zake zogwira ntchito zimatha kunyamulidwa bwino kupita ku gawo lililonse la minofu ya chomera. Makamaka, kuwongolera nsabwe za m'masamba, tizilombo, obzala mpunga, tizilombo toyambitsa matenda ndi tizilombo tina toluma kunali kothandiza kwambiri. Kuphatikiza apo, ingathandizenso kuletsa kuyamwa kwa tizilombo.

1. Mbewu zamasamba (pogwiritsa ntchito 1% granules ndi 20% granules zosungunuka m'madzi): 1% granules zitha kusakanikirana ndi dothi la nthaka pobzala zipatso ndi ndiwo zamasamba ndi ndiwo zamasamba, kapena kusakaniza ndi dothi m'mabowo obzala m'manja pobzala. Izi zitha kuletsa tizilombo toyambitsa matenda panthawi yobzala ndi tizilombo touluka tisanabzalidwe. Kuphatikiza apo, chifukwa mankhwalawa ali ndi mphamvu yabwino yoyamwa ndi kuyendetsa bwino, amatha kuyamwa mwachangu ndi zomera pambuyo pa chithandizo, ndipo amatha kukhalabe ndi mphamvu kwa milungu 4 mpaka 6.

Ma granule 20% osungunuka m'madzi angagwiritsidwe ntchito ngati mankhwala ophera tizirombo ndi tsinde kuti athetse tizirombo. Njira ziwiri zochiritsira, "mankhwala ophera tizilombo" ndi "mankhwala ophera tizilombo m'nthaka panthawi yomera", zikuyesedwa. Ma granule omwe atchulidwa pamwambapa akhoza kuphatikizidwa ndi ma granule osungunuka m'madzi kuti athe kugwiritsidwa ntchito kuyambira pachiyambi cha kukula kwa mbewu mpaka nthawi yokolola.

2. Mitengo ya zipatso (20% ya tinthu tosungunuka m'madzi): Tinthu tosungunuka m'madzi timagwiritsidwa ntchito ngati mankhwala ochizira tsinde ndi masamba pamene tizilombo toyambitsa matenda tayamba, zomwe zimatha kulamulira bwino nsabwe za m'masamba, tizilombo toyamwa tofiira, tizilombo toyambitsa matenda, ndi tizilombo ta lepidoptera. Kuphatikiza apo, ilinso ndi mphamvu yabwino yopha tizilombo toyambitsa matenda pa tizilombo toyambitsa matenda, komanso imaletsa kwambiri kuyamwa. Palibe vuto pa mbewu pamene mlingo ukugwiritsidwa ntchito, ndipo mbewu zimakhalanso zambiri pamene mlingowo wawirikiza kawiri. Monga momwe zimagwiritsidwira ntchito pa mbewu zamasamba, zimakhala ndi mphamvu yolowa m'malo ndi kusamuka kuchokera pamwamba pa tsamba kupita mkati mwa tsamba. Nthawi yomweyo, pali adani achilengedwe ofunikira kwambiri ku mitengo ya zipatso.

3, Mpunga (2% tinthu ta mbande, 1% tinthu ta granule, 0.5% ufa wa DL): Mukagwiritsidwa ntchito mu mpunga, ufa wa DL ndi tinthu ta granule tingagwiritsidwe ntchito mu mlingo wa 30kg/hm2 (chosakaniza chogwira ntchito 10 ~ 20g/hm2), chomwe chingathetse bwino nyongolotsi za zomera, chimbalangondo chakuda, tizilombo ta matope a mpunga ndi tizilombo tina. Makamaka pa tizilombo toyambitsa matenda, kusiyana kwa mphamvu ya mankhwala pakati pa mitundu ya tizilombo ndi kochepa kwambiri. Pambuyo pogwiritsa ntchito bokosi la mbewu, limatha kuwongolera bwino chimbalangondo cha planthopper, chimbalangondo chakuda, chimbalangondo cha mpunga ndi chimbalangondo cha madzi a mpunga mutabzala. Mankhwalawa ali ndi mphamvu yayitali pa tizilombo tomwe tikufuna, ndipo amatha kuwongolera bwino kuchuluka kwa tizilombo patatha masiku 45. Pakadali pano, mayeso ena akuchitidwa pa tizilombo monga Borer, rice borer ndi rice black bug.
