Uburyo bwo gukoresha Dinotefuran

Ubwoko bw'udukoko twica udukokoDinotefuranni nini cyane, kandi nta bushobozi bwo guhangana n’ibintu bikunze gukoreshwa, kandi ifite ubushobozi bwo kwinjiza no kuyobora neza imbere mu mubiri, kandi ibice byayo bishobora gutwarwa neza muri buri gice cy’ibimera. By’umwihariko, kurwanya udukoko, udukoko, ibimera by’umuceri, udukoko twa thrips n’utundi dukoko turumira byari byiza cyane. Byongeye kandi, bishobora no kugera ku ngaruka nziza zo kubuza udukoko kwiyonka.

1. Ibihingwa by'imboga (bikoresha utunyangingo twa l% na 20% by'utunyangingo dushongera mu mazi): utunyangingo twa l% dushobora kuvangwa n'ubutaka bw'ubutaka mu gihe cyo gutera imbuto n'imboga n'imboga z'amababi, cyangwa tukavangwa n'ubutaka mu miferege yo gutera intoki mu gihe cyo gutera. Ibi bishobora kurwanya udukoko twangiza udukoko mu gihe cyo gutera ibiti n'udukoko tuguruka mbere yo gutera ibiti. Byongeye kandi, kubera ko umuti ugira ingaruka nziza zo kwinjiza no kuyobora, ushobora kwinjizwa vuba n'ibimera nyuma yo kuvurwa, kandi ushobora kugumana imbaraga mu gihe cy'ibyumweru 4 kugeza kuri 6.

Uduce duto dushongesha amazi 20% dushobora gukoreshwa nk'imiti ivura udukoko duto n'amababi mu kurwanya udukoko. Uburyo bubiri bwo kuvura, “gutunganya imyanda” n' “gutunganya imyanda mu butaka mu gihe cyo gukura”, burimo kugeragezwa. Uduce duto twavuzwe haruguru dushobora guhuzwa n'uduce duto dushongesha amazi kugira ngo tubashe gukoreshwa kuva igihingwa gitangiye gukura kugeza igihe cyo gusarura.

2. Ibiti by'imbuto (20% by'udukoko dushonga mu mazi): Udukoko dushonga mu mazi dukoreshwa nk'imiti yo kuvura ibiti n'amababi iyo udukoko duteye, dushobora kurwanya neza udukoko two mu bwoko bwa aphids, udukoko two mu bwoko bwa red scale, udukoko two mu biribwa, n'udukoko twa lepidoptera. Byongeye kandi, bigira ingaruka nziza zo kwica udukoko two mu bimera, kandi bibuza cyane ko dushonga. Nta ngaruka mbi ku bihingwa iyo bikoreshejwe, kandi imyaka nayo iba myinshi iyo ingana kabiri. Nkuko bikoreshwa ku bihingwa by'imboga, bigira ingaruka zo kwinjira no kwimuka kuva ku buso bw'amababi ujya ku mababi imbere. Muri icyo gihe, hari abanzi b'ingenzi ku biti by'imbuto.

3, Umuceri (2% by'uduti two mu gasanduku k'imbuto, l% by'uduti two mu bwoko bwa DL, 0.5% by'ifu ya DL): Iyo ukoreshejwe mu muceri, ifu ya DL n'uduti two mu bwoko bwa 30kg/hm2 (ikintu cy'ingenzi 10 ~ 20g/hm2), bishobora kurwanya neza inzoka zo mu bimera, ihori ry'umukara, udukoko two mu mukungugu n'utundi dukoko. Cyane cyane ku dukoko duto, itandukaniro ry'imiti hagati y'ubwoko ni rito cyane. Nyuma yo gukoresha agasanduku k'imbuto, gashobora kurwanya neza ihori ry'umukara, ihori ry'umukara, ihori ry'umuceri n'ihori ry'umuceri nyuma yo guterwa. Uyu muti ugira ingaruka ndende ku dukoko twibasiwe, kandi ushobora kugenzura neza ubucucike bw'udukoko nyuma y'iminsi 45. Kuri ubu, hari izindi geragezwa zirimo gukorwa ku dukoko nka Borer, rice borer na rice black bug.
