ʻO ka maʻi bacterial soybean he maʻi mea kanu pōʻino e pili ana i nā mea kanu soya ma ka honua holoʻokoʻa.Hoʻokumu ʻia ka maʻi e kahi huakino i kapa ʻia ʻo Pseudomonas syringae PV.Hiki i ka Soybeans ke lilo i ka nui o ka hua ke waiho ʻole ʻia.Ke ʻimi nei ka poʻe mahiʻai a me nā ʻoihana mahiʻai i nā ala kūpono e hakakā ai i ka maʻi a mālama i kā lākou mea kanu soya.Ma kēia ʻatikala, ʻimi mākou i nā fungicides kemika streptomycin, pyraclostrobin, a me copper oxychloride a me kā lākou hiki ke mālama i ka maʻi bacterial soybean.

ʻO Streptomycin kahi pūhui multifunctional i hoʻohana nui ʻia ma ke ʻano he lāʻau antibiotic i nā kānaka.Eia nō naʻe, hoʻohana ʻia ia ma ke ʻano he pesticide mahiʻai.Loaʻa iā Streptomycin nā waiwai antimicrobial ākea ākea a maikaʻi i ka hoʻopaʻa ʻana i ka bacteria, fungi a me nā algae.I ka hihia o ka maʻi bacteria soybean, ua hōʻike ʻo streptomycin i nā hopena maikaʻi i ka hoʻomalu ʻana i ka maʻi bacteria e kumu ai ka maʻi.Hiki ke hoʻohana ʻia ma ke ʻano he foliar spray e hōʻemi pono i ka paʻakikī a me ka hoʻolaha ʻana o ka maʻi.Hiki nō hoʻi iā Streptomycin ke hoʻomalu i nā maʻi bacteria a me nā fungal o nā mea kanu ʻē aʻe, a me ka ulu ʻana o nā algae i loko o nā loko nani a me nā aquarium.

 

Copper oxychlorideʻO ia kekahi fungicide kemika i hoʻohana nui ʻia i ka mahiʻai no ka mālama ʻana i nā maʻi fungal a me nā maʻi bacteria i nā huaʻai a me nā mea kanu mea kanu, me ka soybeans.He mea maikaʻi loa ia e kūʻē i nā maʻi e like me ka blight, mold, a me ka lau lau.Ua hōʻike ʻia ʻo Copper oxychloride e kūʻē iā Pseudomonas syringae pv.Soybean, ke kumu kumu o ka ma'i bacteria o ka soybean.Ke hoʻohana ʻia ma ke ʻano he ʻōpala, hana kēia fungicide i kahi papa pale ma luna o nā mea kanu, pale i ka ulu a me ka laha ʻana o nā pathogens.ʻO kona hiki ke hāʻawi i ka pale mau loa he koho maikaʻi loa ia no ka pale ʻana a me ka mālama ʻana i ka maʻi bacterial soybean.

Pyraclostrobinhe fungicide i hoʻohana mau ʻia i ka mahiʻai a hoʻohana nui ʻia no ka mālama ʻana i nā maʻi kanu like ʻole.No nā kemika strobilurin ka fungicide a he mea maikaʻi loa ia e kūʻē i nā pathogen fungal.Hana ʻo Pyraclostrobin ma ke kāohi ʻana i ke kaʻina hana hanu o nā sela fungal, me ka pale ʻana i ko lākou ulu ʻana a me ka hana hou ʻana.ʻOiai ʻaʻole hiki i ka pyraclostrobin ke kuhikuhi pololei i ka maʻi bacteria e hoʻoulu ai i ka maʻi bacterial soybean, ua hōʻike ʻia he hopena ʻōnaehana hiki ke hōʻemi pololei i ka nui o ka maʻi.ʻO kona hiki ke hoʻomalu i nā maʻi fungal ʻē aʻe o nā mea kanu soy e lilo ia i mea waiwai nui i kahi ala hoʻokele maʻi hoʻohui.

Ke koho ʻana i nā fungicides kemika e mālama i ka maʻi bacterial soybean, pono e noʻonoʻo ʻia nā mea e like me ka pono, palekana, a me ka hopena o ke kaiapuni.ʻO Streptomycin, copper oxychloride, a me pyraclostrobin nā koho kūpono a pau i ka hakakā ʻana i kēia maʻi pōʻino.Eia nō naʻe, pono e kūkākūkā ʻia ke koho o nā fungicides me nā loea mahiʻai, e like me nā kūlana kikoʻī a me nā koi o nā mea kanu soy.Eia hou, he mea koʻikoʻi ka hahai ʻana i nā helu noi i ʻōlelo ʻia a me nā kaʻina palekana e hōʻemi i nā pilikia e pili ana i ka hoʻohana ʻana i kēia mau kemika.

 

I ka hopena, ʻo ka maʻi bacterial o ka soybean kahi hopohopo nui no nā mea kanu soy a hiki i nā fungicide kemika ke hana koʻikoʻi i kāna hoʻokele.ʻO Streptomycin, copper oxychloride, a me pyraclostrobin nā mea kemika a pau i hiki ke hana maikaʻi i ka pale ʻana i ka maʻi.Eia nō naʻe, pono e noʻonoʻo ʻia nā mea e like me ka pono, palekana, a me ka hopena o ke kaiapuni i ke koho ʻana i ka fungicide kūpono loa no ka mālama ʻana i ka maʻi bacterial soybean.Ma ka hoʻokō ʻana i nā hoʻolālā hoʻokele maʻi i hoʻohui ʻia a me ka hoʻohana ʻana i nā fungicides kūpono, hiki i ka poʻe mahiʻai ke pale i nā mea kanu soy a hōʻoia i ka ʻohi maikaʻi.
