ʻO ka laulā o nā mea pepehi insecticidalʻO DinotefuranHe ākea loa ia, ʻaʻohe pale kūʻē i nā mea i hoʻohana pinepine ʻia, a he hopena omo a me ka hoʻokele kūloko maikaʻi kona, a hiki ke lawe maikaʻi ʻia nā ʻāpana pono i kēlā me kēia ʻāpana o ka ʻiʻo mea kanu. ʻOi aku ka maikaʻi o ka kaohi ʻana i nā aphids, nā pepeke, nā mea kanu laiki, nā thrips a me nā pepeke ʻē aʻe. Eia kekahi, hiki iā ia ke hoʻokō i kahi hopena pololei o ka pale ʻana i ka omo ʻana o nā mea ʻino.
1. Nā mea kanu huaʻai (me ka hoʻohana ʻana i ka 1% granules a me 20% granules wai-soluble): hiki ke hoʻohuihui ʻia ka 1% granules me ka lepo lua lepo i ka wā o ke kanu ʻana i nā huaʻai a me nā mea kanu a me nā lau nahele, a i ʻole e hui pū ʻia me ka lepo i loko o nā ʻauwaha lūlū lima i ka wā o ka lūlū ʻana. Hiki i kēia ke kāohi i nā mea ʻino parasitic i ka wā o ke kanu ʻana a me nā mea ʻino e lele ana ma mua o ke kanu ʻana. Eia kekahi, no ka mea he hopena omo a me ka hoʻokele maikaʻi ka lāʻau, hiki ke omo koke ʻia e nā mea kanu ma hope o ka mālama ʻana, a hiki ke mālama i ka pono no 4 a 6 mau pule.
Hiki ke hoʻohana ʻia he 20% o nā granules wai-hoʻoheheʻe ʻia ma ke ʻano he mau mea lapaʻau kumu a me lau e kāohi ai i nā mea ʻino. Ke hoʻāʻo ʻia nei ʻelua mau ʻano lapaʻau, ʻo ia hoʻi ka "perfusion treatment" a me ka "soil perfusion treatment during growth period". Hiki ke hoʻohui ʻia nā granules i ʻōlelo ʻia ma luna me nā granules wai-hoʻoheheʻe ʻia i hiki ke hoʻopili ʻia mai ka hoʻomaka ʻana o ka ulu ʻana o nā mea kanu a hiki i ka ʻohi ʻana.
2. Nā lāʻau hua (20% granules wai-hoʻoheheʻe ʻia): Hoʻohana ʻia nā granules wai-hoʻoheheʻe ʻia ma ke ʻano he mau mea lapaʻau kumu a me lau ke loaʻa nā mea ʻino pepeke, hiki ke kāohi pono i nā aphids, nā pepeke omo o ka unahi ʻulaʻula, nā pepeke meaʻai, a me nā mea ʻino lepidoptera. Eia kekahi, he hopena insecticidal maikaʻi hoʻi ia i nā mea ʻino pepeke, a he kāohi kiʻekiʻe i ka omo ʻana. ʻAʻohe pōʻino i nā mea kanu ke hoʻohana ʻia ka nui, a ʻoi aku ka nui o nā mea kanu ke pāpālua ka nui. E like me ka hoʻohana ʻia ʻana ma nā mea kanu mea kanu, loaʻa iā ia ka hopena o ka komo ʻana a me ka neʻe ʻana mai ka ʻili lau a i ka lau i loko. I ka manawa like, aia nā ʻenemi kūlohelohe koʻikoʻi i nā lāʻau hua.
3, Laiki (2% granules pahu hua kanu, l% granules, 0.5% pauka DL): Ke hoʻohana ʻia i ka laiki, hiki ke hoʻohana ʻia ka pauka DL a me nā granules i ka nui o 30kg/hm2 (mea hana pono 10 ~ 20g/hm2), hiki ke kāohi pono i nā ilo mea kanu, ka ʻūlū lau huelo ʻeleʻele, nā pepeke lepo laiki maikaʻi ʻole a me nā mea ʻino ʻē aʻe. ʻOi loa no nā mea ʻino pepeke, he liʻiliʻi loa ka ʻokoʻa o ka pono o ka lāʻau ma waena o nā ʻano. Ma hope o ka hoʻohana ʻana i ka pahu hua kanu, hiki iā ia ke kāohi pono i ka ʻūlū mea kanu, ka ʻūlū lau huelo ʻeleʻele, ka ʻūlū laiki a me ka borer wai paipu laiki ma hope o ke kāpili ʻana. Loaʻa i ka lāʻau kahi hopena lōʻihi ma nā mea ʻino i manaʻo ʻia, a hiki nō ke kāohi pono i ka nui o ka heluna pepeke ma hope o 45 mau lā. I kēia manawa, ke hana ʻia nei nā hoʻāʻo hou aʻe ma nā mea ʻino e like me Borer, borer laiki a me ka ʻūlū ʻeleʻele laiki.
