Uhlu lwama-insecticidalI-Dinotefuranibanzi uma kuqhathaniswa, futhi akukho ukumelana nesiphambano kuma-ejenti asetshenziswa ngokuvamile, futhi inomphumela omuhle wokumunca wangaphakathi nowokuqhuba, futhi izingxenye ezisebenzayo zingathuthwa kahle ziye kuzo zonke izingxenye zezicubu zesitshalo. Ikakhulukazi, ukulawulwa kwama-aphid, izimbungulu, izitshalo zokutshala irayisi, ama-thrips nezinye izinambuzane ezihlabayo kwakusebenza kakhulu. Ngaphezu kwalokho, ingakwazi futhi ukufeza umphumela onembe kakhudlwana wokuvimbela ukumunca izinambuzane.
1. Izitshalo zemifino (usebenzisa i-l % granules kanye nama-granules angu-20% ancibilikayo emanzini) : I-l % granules ingaxutshwa nenhlabathi yembobo yomhlabathi ngesikhathi sokufakelwa kabusha kwezithelo nemifino nemifino enamaqabunga, noma ihlanganiswe nenhlabathi emiseleni yokuhlwanyela esandleni ngesikhathi sokuhlwanyela. Lokhu kungalawula izinambuzane eziwuhlupho ngesikhathi sokutshala kabusha kanye nezilokazane ezindiza ngaphambi kokutshala. Ngaphezu kwalokho, ngenxa yokuthi umuthi unomphumela omuhle wokumuncwa kanye nowokuqhuba, ungamuncwa ngokushesha izitshalo ngemva kokwelashwa, futhi ungagcina ukusebenza kahle kwamaviki angu-4 kuya kwangu-6.
Ama-granules angu-20% ancibilika emanzini angasetshenziswa njengama-ejenti okwelapha isiqu namaqabunga ukulawula izinambuzane. Izindlela zokwelapha ezimbili, “ukwelashwa nge-perfusion” kanye “nokwelashwa ngokufaka inhlabathi ngesikhathi sokukhula”, ziyahlolwa. Ama-granules ashiwo ngenhla angahlanganiswa nama-granules ancibilika emanzini ukuze asetshenziswe kusukela ekuqaleni kokukhula kwezitshalo kuze kufike ekuvuneni.
2. Izihlahla zezithelo (ama-granules angu-20% ancibilika emanzini) : Ama-granules ancibilikayo emanzini asetshenziswa njengama-ejenti okwelapha isiqu namaqabunga lapho izinambuzane zenzeka, ezingalawula ngempumelelo ama-aphid, izinambuzane ezimunca isikali esibomvu, izinambuzane zokudla, nezinambuzane ze-lepidoptera. Ngaphezu kwalokho, iphinde ibe nomphumela omuhle wokubulala izinambuzane ezinambuzaneni zezinambuzane, kanye nokuvimbela okuphezulu kokumunca. Akukho monakalo ezitshalweni lapho umthamo usetshenziswa, futhi izitshalo nazo ziba ngaphezulu lapho umthamo uphindwe kabili. Njengoba isetshenziswa ezitshalweni zemifino, inomphumela wokungena nokufuduka ukusuka endaweni yamaqabunga kuya eqabungeni ngaphakathi. Ngesikhathi esifanayo, kunezitha zemvelo ezibaluleke kakhulu ezihlahleni zezithelo.
3, Ilayisi (ama-granules angu-2% webhokisi lezithombo, l % ama-granules, 0.5% DL powder) : Uma isetshenziswa elayisini, i-DL powder kanye nezinhlamvana zingasetshenziswa kumthamo ongu-30kg/hm2 (isithako esisebenzayo 10 ~ 20g/hm2), esingalawula ngempumelelo amahlamvu e-plantrice, i-black-tailed leaf, i-black-tailed. izinambuzane. Ikakhulukazi ezinambuzaneni zezinambuzane, umehluko wokusebenza kwezidakamizwa phakathi kwezinhlobo zezilwane mncane kakhulu. Ngemuva kokusetshenziswa kwebhokisi lezithombo, lingalawula ngempumelelo i-planthopper, i-leafhopper enomsila omnyama, isinambuzane selayisi kanye ne-rice tube water borer ngemva kokufakelwa kabusha. Umuthi unomphumela omude osalayo ezinambuzaneni ezihlosiwe, futhi usengakwazi ukulawula ngempumelelo ukuminyana kwezinambuzane ngemva kwezinsuku ezingu-45. Njengamanje, kwenziwa ezinye izivivinyo ezinambuzaneni ezifana ne-Borer, i-rice borer kanye ne-rice black bug.
