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 ngamaxesha 2000 kuya kusetyenziswa ngokulinganayo 30 amaxesha ukuya 30 ukuhoywa iya kusetyenziswa ngamaxesha angama-30. kuhlawulwe kwisitshizi esifanayo kumphezulu wegqabi nasemva ukuze kuqinisekiswe ukusebenza kakuhle kunye nokulawula.

Intshulube

Iimpawu zokwenzakala:

Yeyomyalelo weLepidoptera kunye nosapho lweNoctidae. Yeyona nkathazo iphambili ngexesha le-cotton bud kunye ne-boll stage. Imibungu ilimaza iingcebiso zethenda, iintyatyambo, iintyatyambo kunye neebholi eziluhlaza zomqhaphu, kwaye zinokuluma umphezulu weziqu zethenda ezimfutshane, zenze umqhaphu ongenantloko. 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 nesesine isizukulwana somqhaphu sibuthathaka, kwaye ulawulo lwangexesha luyimfuneko.Iyeza linokuba yi-35% yepropafenone • phoxim 1000-1500 amaxesha, 52.25% chlorpyrifos • chlorpyrifos 1000-1500 amaxesha, kunye 20% chlorrifos 10pylopy 10py010 chlorrifos 10py010 chlorrifos 10py0pyrifos 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 amaqabunga kunye namaqabunga kunye neebholi, ngokutya ngokukrakra amaqabunga kunye nokonakalisa amaqabunga kunye neebholi, ezibangela ukuba zibole okanye ziwe.Xa zilimaza iibholi zekotoni, kukho i-boreholes eyi-1-3 kwisiseko sebholi, kunye nobukhulu obungaqhelekanga kunye nobukhulu be-pore, kunye nezinambuzane ezinkulu zezinambuzane ezifakwe ngaphandle kwemingxuma. 

Uthintelo kunye nolawulo lwekhemikhali:

Amayeza kufuneka alawulwe ngexesha lamanyathelo okuqala ombungu kwaye acinywe ngaphambi kwexesha lokutya. Ekubeni imibungu ingaphumi emini, ukutshiza kufuneka kuqhutywe ngokuhlwa.Iyeza liya kuba yi-35% probromine • phoxim 1000-1500 amaxesha, 52.25% chlorpyrifos • cyanogen chloride 1000-1500 amaxesha, 20% chlori0000, amaxesha 10 chlorifoll, 10 chlorifoll kunye 1 ngokulinganayo ukutshizwa.
