Uluhlu lwezinambuzane ezibulala izinambuzaneI-Dinotefuranibanzi kakhulu, kwaye akukho ukumelana okunqamlezileyo kwizinto ezisetyenziswa rhoqo, kwaye inefuthe elihle lokufunxa kwangaphakathi kunye nokuqhuba kwayo, kwaye izinto ezisebenzayo zinokuthuthwa kakuhle kuyo yonke indawo yezicubu zesityalo. Ngokukodwa, ulawulo lwee-aphids, iincukuthu, izityalo zerayisi, ii-thrips kunye nezinye izinambuzane ezihlabayo belusebenza ngakumbi. Ngaphezu koko, inokufezekisa isiphumo esichanekileyo ngakumbi sokuthintela ukufunxa izinambuzane.
1. Izityalo zemifuno (ezisebenzisa ii-granules ezili-1% kunye nee-granules ezingama-20% ezinyibilikayo emanzini): ii-granules ezili-1% zingaxutywa nomhlaba onomngxuma womhlaba ngexesha lokutyala iziqhamo nemifuno kunye nemifuno enamagqabi, okanye zixutywe nomhlaba okwimisele yokutyala ngesandla ngexesha lokutyala. Oku kunokulawula izinambuzane ezidla izimuncu ngexesha lokutyala kunye nezinambuzane ezibhabhayo ngaphambi kokutyala. Ukongeza, kuba iyeza linefuthe elihle lokufunxa kunye nokuqhuba, linokufunxwa ngokukhawuleza zizityalo emva konyango, kwaye linokugcina ukusebenza kakuhle iiveki ezi-4 ukuya kwezi-6.
Iigranule ezingama-20% ezinyibilikayo emanzini zingasetyenziswa njengezixhobo zonyango lweziqu namagqabi ukulawula izinambuzane. Iindlela ezimbini zonyango, "unyango lokufunxa amanzi" kunye "nonyango lokufunxa umhlaba ngexesha lokukhula", ziyavavanywa. Ezi granule zikhankanyiweyo apha ngasentla zingadityaniswa neegranule ezinyibilikayo emanzini ukuze zisetyenziswe ukususela ekuqaleni kokukhula kwesityalo kude kube sekuvunweni.
2. Imithi yeziqhamo (20% yeegranules ezinyibilikayo emanzini): Iigranules ezinyibilikayo emanzini zisetyenziswa njengezixhobo zonyango lweziqu namagqabi xa kuvela izinambuzane, ezinokulawula ngempumelelo ii-aphids, izinambuzane ezifunxayo ze-red scale, izinambuzane zokutya, kunye nezinambuzane ze-lepidoptera. Ukongeza, ikwanayo nefuthe elihle lokubulala izinambuzane kwizinambuzane, kwaye iyathintela kakhulu ukufunxa. Akukho monakalo kwizityalo xa kusetyenziswa idosi, kwaye izityalo nazo ziba ninzi xa idosi iphindwe kabini. Njengoko isetyenziswa kwizityalo zemifuno, inefuthe lokungena nokufuduka ukusuka kumphezulu wegqabi ukuya kwigqabi ngaphakathi. Kwangaxeshanye, kukho iintshaba zendalo ezibalulekileyo kwimithi yeziqhamo.
3, Irayisi (2% iigranules zebhokisi yembewu, iigranules ezili-1%, umgubo we-DL ongu-0.5%): Xa isetyenziswa kwirayisi, umgubo we-DL kunye neegranules zingasetyenziswa kwi-30kg/hm2 dosage (isithako esisebenzayo yi-10 ~ 20g/hm2), enokulawula ngempumelelo iimpethu zezityalo, i-black-tailed leafhopper, izinambuzane zodaka olungenalo irayisi kunye nezinye izinambuzane. Ingakumbi kwizinambuzane ezitshabalalisa izinambuzane, umahluko wokusebenza kwamayeza phakathi kweentlobo mncinci kakhulu. Emva kokusetyenziswa kwebhokisi yezityalo, inokulawula ngempumelelo i-planthopper, i-black-tailed leafhopper, i-rice bug kunye ne-rice tube water borer emva kokufakelwa. Eli yeza linefuthe elide kwizinambuzane ekujoliswe kuzo, kwaye lisenokulawula ngempumelelo ubuninzi bezinambuzane emva kweentsuku ezingama-45. Okwangoku, kwenziwa olunye uvavanyo kwizinambuzane ezifana neBorer, i-rice borer kunye ne-rice black bug.
