Izifo zoMqhaphu eziphambili kunye neZitshabalalisi kunye noThintelo noLawulo lwazo (2)

Intwala yomqhaphu

Iimpawu zokwenzakala:

Iintwala zomqhaphu zigqobhoza umva wamagqabi womqhaphu okanye iintloko ezithambileyo ngomlomo ohlabayo ukuze zifunxe ijusi.Ichaphazeleka ngexesha lenqanaba lezithole, umqhaphu ushiya i-curl kwaye ixesha leentyatyambo kunye ne-boll setting lilibazisekile, okukhokelela ekuvuthweni kade kunye nokuncipha kwesivuno;Ukuchaphazeleka ngexesha lenqanaba labantu abadala, amaqabunga aphezulu aphelile, amaqabunga aphakathi abonakala enamafutha, kwaye amaqabunga aphantsi abuna kwaye awele;Iibhondi ezonakalisiweyo kunye neebholi zinokuwa ngokulula, ezichaphazela ukuphuhliswa kwezityalo zekotoni;Ezinye zibangela amagqabi awileyo kwaye zinciphisa imveliso.

Uthintelo kunye nolawulo lwekhemikhali:

I-10% imidacloprid 20-30g nge-mu, okanye i-30% imidacloprid 10-15g, okanye i-70% imidacloprid 4-6 g nge-mu, ngokulinganayo ukutshiza, umphumo wokulawula ufikelela kwi-90%, kwaye ubude bungaphezu kweentsuku ze-15.

I-Spider Mite enamachaphaza amabini

Iimpawu zokwenzakala:

Izinambuzane zesigcawu ezinamachokoza amabini, ezaziwa ngokuba ziidragons zomlilo okanye izigcawu zomlilo, zixhaphakile kwiminyaka yembalela kwaye zitya kakhulu ijusi esemva kwamagqabi womqhaphu;Ingenzeka ukusuka kwinqanaba lokugalela ukuya kutsho kwinqanaba lokuvuthwa, kunye namaqela eentwala kunye namangolwane aqokelelana ngasemva emagqabini ukuze afunxe ijusi.Amagqabi awonakeleyo womqhaphu aqala ukubonisa amabala atyheli namhlophe, kwaye xa umonakalo usiba mandundu, kuvela amabala abomvu emagqabini de igqabi lonke lijike libe mdaka libune kwaye liwe.

Uthintelo kunye nolawulo lwekhemikhali:

Kumaxesha onyaka ashushu nembalela, 15% pyridaben 1000 ukuya 1500 amaxesha, 20% pyridaben 1500 ukuya 2000 amaxesha, 10.2% avid pyridaben 1500 ukuya 2000 amaxesha, kunye 1.8% ngokungxamisekileyo 2000 ngendlela elinganayo 2000 ngamaxesha ukuya 30 ngamaxesha ukuya 30 amaxesha ukuya 30 kwaye ingqwalasela iya kuhlawulwa kwisitshizi esifanayo kumphezulu weqabunga kunye nomqolo ukuqinisekisa ukusebenza kunye nokulawula umphumo.

Intshulube

Iimpawu zokwenzakala:

Yeyomyalelo weLepidoptera kunye nosapho lweNoctidae.Yeyona nkathazo iphambili ngexesha le-cotton bud kunye ne-boll stage.Imibungu iyawonakalisa iincam zethenda, amagqabi, iintyatyambo, kunye neebholi eziluhlaza zomqhaphu, kwaye zinokuluma umphezulu weziqu ezimfutshane zethenda, zenze umqhaphu ongenantloko. okanye iintsuku ezintathu.Imibungu ikhetha ukutya umungu kunye nebala.Emva kokonakala, iibholi eziluhlaza zingenza amabala abolileyo okanye aqinile, achaphazela kakhulu isivuno sekotoni kunye nomgangatho.

Uthintelo kunye nolawulo lwekhemikhali:

Umqhaphu onganyangekiyo kwizinambuzane unempembelelo elungileyo yokulawula kwisizukulwana sesibini somqhaphu wekotoni, kwaye ngokubanzi awufuni lawulo.Impembelelo yokulawula kwisizukulwana sesithathu nesine isizukulwana somqhaphu sibuthathaka, kwaye ulawulo lwangexesha luyimfuneko.Iyeza linokuba yi-35% propafenone • phoxim 1000-1500 amaxesha, 52.25% chlorpyrifos • chlorpyrifos 1000-1500 amaxesha, kunye 20% chlorrifos chlorifos 1000-1500 amaxesha.

Spodoptera litura

Iimpawu zokwenzakala:

Imibungu esanda kuqanduselwa iqokelelana kwaye itya i-mesophyll, ishiya ngasemva i-epidermis okanye imithambo ephezulu, yenze i-sieve efana nenethiwekhi yeentyatyambo kunye namagqabi.Emva koko basasaza kwaye bawonakalise amagqabi kunye ne-buds kunye neebholi, ngokutshabalalisa amagqabi kunye nokonakalisa amaqabunga kunye neebholi, ezibangela ukuba zibole okanye ziwe. ubungakanani obungaqhelekanga kunye nobukhulu bomngxuma, kunye nelindle lezinambuzane ezinkulu ezifunjwe ngaphandle kwemingxuma. 

Uthintelo kunye nolawulo lwekhemikhali:

Amayeza kufuneka alawulwe ngexesha lamanyathelo okuqala ombungu kwaye acinywe ngaphambi kwexesha lokutya.Ekubeni imibungu ingaphumi emini, ukutshiza kufuneka kwenziwe ngokuhlwa.Iyeza liya kuba yi-35% probromine • phoxim 1000-1500 amaxesha, 52.25% chlorpyrifos • cyanogen chloride 1000-1500 amaxesha, 20% chlorifoll • Amaxesha angama-1000-1500, kunye nokutshizwa ngokulinganayo.
