Yeyiphi impembelelo yesibulali zinambuzane eyomeleleyo, iLufenuron okanye iChlorfenapyr?

Lufenuron

I-Lufenuron luhlobo olusebenzayo oluphezulu, i-spectrum ebanzi kunye ne-low toxicity insecticide yokuthintela ukunyibilika kwezinambuzane.Ikakhulu inetyhefu yesisu, kodwa ikwanefuthe elithile lokuchukumisa.Ayinamdla wangaphakathi, kodwa inesiphumo esihle.Impembelelo yeLufenuron kwimibungu emincinci ilungile ngakumbi.Emva kokutya izityalo ezifafazwe nge-pesticide, izinambuzane ziyeka ukutya kwiiyure ezingama-2 kwaye zingene kwincopho yezinambuzane ezifileyo kwiintsuku ezingama-2-3.

Ikhuselekile kwiintshaba ezininzi zendalo ngenxa yokusebenza kwayo kancinci kunye nexesha elide lesenzo.

I-Chlorfenapyr

I-Chlorfenapyr inefuthe elithile kumsebenzi we-ovicidal.Xa kudityaniswe nentelekelelo kunye noqikelelo lwezitshabalalisi, kucetyiswa ukuba isitshizi sinokudlala isiphumo esilungileyo solawulo kwincopho yokuqanduselwa kwezinambuzane okanye ukuqanduselwa kwamaqanda.

I-Chlorfenapyr ine-conductivity efanelekileyo yendawo kwizityalo, kwaye umphumo ofanayo unokufumaneka kwi-underside yamagqabi ezondliwe zizinambuzane.

Isiphumo solawulo yi-90-100% phakathi kweentsuku ze-L-3 emva kwechiza, kwaye umphumo usazinzile kwi-90% phakathi kweentsuku ezili-15 emva kwechiza.Umthamo onconywayo ngu-30-40 ml nge-mu, kunye nekhefu leentsuku ezingama-15-20.

Ingqwalasela ekhethekileyo kufuneka ihlawulwengelixa usebenzisa iChlorfenapyr:

1) Inochuku kwivatala, i-zucchini, i-gourd ekrakra, i-melon, i-cantaloupe, i-white gourd, ithanga, i-cantaloupe, i-loofah kunye nezinye izityalo.Akukhuthazwa kwinqanaba lamagqabi amancinci.

2) Gwema ukusebenzisa iziyobisi kwiqondo lokushisa eliphezulu, isigaba seentyantyambo kunye nesigaba seedling;

Umahluko phakathiChlorfenapyr kunyeLufenuron

1. Iindlela zokubulala izinambuzane

I-Lufenuron inefuthe letyhefu yesisu kunye nokuchukumisa, akukho mnqweno wangaphakathi, ukubulawa kweqanda elinamandla;

I-Chlorfenapyr inetyhefu yesisu kunye ne-tactility, kwaye inokufunxa okuthile kwangaphakathi.

Ukusetyenziswa kwe-osmotic / extender agents (umzekelo, i-silicone) iya kwandisa kakhulu ukusebenza kokubulala.

2. I-spectrum ye-insecticidal

Isetyenziswa ikakhulu kulawulo lwe-leaf roller, iPlutella xylostella, i-Rapeseed, i-beet armyworm, iSpodoptera litura, i-whitefly, ithrips, amakhalane kunye nezinye izinambuzane, ngakumbi kulawulo lwe-rice leaf roller.

I-Lufenuron inempembelelo egqwesileyo yokulawula izinambuzane nezinambuzane, ngakumbi kwizitshabalalisi ezixhathisayo ezifana nePlutella xylostella, i-Exigua beet armyworm, i-Exigua chinensis, i-leaf roller, i-American spot miner, i-pod borer, ithrips kunye nesigcawu esineenkwenkwezi.

Ke ngoko, umahluko obanzi ngokwe-insecticidal spectrum yile: Chlorfenapyr> Lufenuron> Indoxacarb

3, Ukubulala isantya

Ukudibana kwezinambuzane kunye ne-pesticide kunye nokutya kwamagqabi kunye ne-pesticide, umlomo uya kuba ne-anesthetized kwiiyure ze-2, uyeke ukondla, ukuze uyeke ukulimaza izityalo, iintsuku ezi-3-5 ukufikelela kwincopho yezinambuzane ezifileyo;

Iyure enye emva kokunyangwa kwe-insecticide fenfenitrile, umsebenzi wezinambuzane waba buthathaka, amabala abonakala, umbala watshintsha, umsebenzi wayeka, i-coma, iqhwala, kwaye ekugqibeleni yakhokelela ekufeni, kwaye incopho yezinambuzane ezifileyo yafikelelwa kwiiyure ezingama-24.

Ngoko ke, ngokwesantya se-insecticidal, uthelekiso kukuba: Chlorfenapyr> Lufenuron

4. Ixesha lokugcinwa

I-Lufenuron inefuthe elinamandla le-ovicidal, kwaye ixesha lokulawula izinambuzane lide, ukuya kwiintsuku ezingama-25;

I-Chlorfenapyr ayibulali amaqanda, kodwa isebenza kuphela kwizinambuzane ezikhulileyo, kwaye ixesha lokulawula li malunga neentsuku ezingama-7-10.

Chlorfenapyr > Lufenuron

5. Izinga lokugcinwa kwamagqabi

Eyona njongo yokubulala izinambuzane kukuthintela izitshabalalisi zingonakalisi izityalo.Ngokubhekiselele kwisantya kunye nokufa okucothayo kwezinambuzane okanye ngaphezulu nangaphantsi, inqanaba lezinga lokukhusela amagqabi lisalathiso sokugqibela sokulinganisa ixabiso lemveliso.

Xa kuthelekiswa nefuthe lokulawula i-rice leaf roller, izinga lokugcinwa kweqabunga le-louciacaride kunye ne-fenfenitrile lifikelele ngaphezu kwe-90% kunye ne-65% ngokulandelanayo.

Ngoko ke, ngokwezinga lokugcinwa kwamagqabi, uthelekiso kukuba: Chlorfenapyr > Lufenuron

6. Ukhuseleko

Ukuza kuthi ga ngoku, akukabikho mpendulo yesibulali-zinambuzane.Kwangaxeshanye, i-insecticide ayiyi kubangela ukuxhaphaka kokugwaza kunye nokufunxa izinambuzane, kwaye inefuthe elincinci kubantu abadala bezinambuzane ezincedo kunye nezigcawu ezidliwayo.

I-Chlorfenapyr inovelwano kwimifuno ye-cruciferous kunye neemelon, kwaye inokubangela umonakalo weziyobisi xa isetyenziswe kwiqondo lokushisa eliphezulu okanye idosi ephezulu.

Ngoko ke, ukuthelekiswa kokhuseleko ngu: Lufenuron > Chlorfenapyr
