Ihlukile ekukhethweni okuningi kwama-ejenti okulawula i-stem borer ezindaweni zerayisi, ngayinye inobuhle bayo kanye nobubi bayo, okwamanje i-pymetrozine kanye nemikhiqizo yayo ehlanganisiwe isathatha ingxenye enkulu yemakethe phakathi kwama-ejenti alawula i-rice planthopper, futhi eminye imikhiqizo ngeke ikwazi ukuyinyakazisa. inombolo eyodwa ukusetshenziswa ngesikhathi esifushane. isimo.

Inkinga yePymetrozine

Njengoba amandla okukhiqiza ezinkampani ezihlukahlukene zemithi yobuchwepheshe ededelwa kancane kancane, ukuncintisana kumakhemikhali asezindaweni kuya ngokuya kushuba. I-Pymetrozine isetshenziswa kakhulu ukulawula izintwala ezindaweni zelayisi nakwezinye izindawo zezihlahla zezithelo. Njengamanje, asikho isiqondiso esisobala lapho umthamo unganyuswa khona, okubangela ukuthi lo mkhiqizo ube ngumkhiqizi womuthi wokuqala. , abakhiqizi bamalungiselelo, ngisho nabasabalalisi nabathengisi bonke behliselwa esimweni lapho inzuzo encane ibe yimikhiqizo yomgwaqo.

Ukushoda kwezinto ezisetshenziswayo ezimbonini ezidinga amandla okuqinile kuzoholela ekwandeni okungahlelekile kwamandla okukhiqiza ohlangothini lokunikezela. Abakhiqizi abaningi bazongena ezimakethe ezishisayo ukuze bancintisane, okuholela emalini yenzuzo emincane nencane. Ngenxa yalokho, i-pymetrozine yedosi eyodwa yaqala ukuncintisana ngentengo, futhi kancane kancane yavela emikhiqizweni ehlanganisiwe, eyaqala ukuncintisana ngentengo. Ngenxa yezizathu eziningi ezifana nokudluliswa kwamandla okukhiqiza, ukuhlolwa okuqinile kokuvikelwa kwemvelo, nokungahleleki kahle kwamaphuzu esikhathi sokuphakela kanye nesidingo, intengo yomuthi wokuqala ishintshile ngaphezu kwalokho obekulindelwe ngumkhiqizi ngamunye, okubangele ukuthi abakhiqizi abangaphansi komfula abasebenzisa i-pymetrozine bawele enkingeni, ikakhulukazi abakhiqizi bokubunjwa ngaphandle kokusekelwa komuthi wokuqala.

Imakethe yerayisi iyindawo yempi yabakhiqizi abaningi, kodwa ngaphandle kwe-triflufenac, eye yathandwa kakhulu eminyakeni yamuva, kubakhiqizi abaningi, ayikho imikhiqizo eminingi emihle kakhulu ngaphandle kwe-pymetrozine yokuvimbela nokulawula ama-planthoppers werayisi. Ukukhuthaza. Ukusebenza kwemakethe kwe-dinotefuran kuhle, kodwa uma kuqhathaniswa ne-pymetrozine, i-dinotefuran ifana kakhulu nomncintiswano omuhle mayelana nokukhushulwa kwangempela, ukusetshenziswa nokusebenza ngempumelelo, hhayi esikhundleni esihlukile, futhi izonyamalala maduzane. Ilandele indlela endala yokuncintisana ngentengo nge-pymetrozine, ngakho ayizange ibe nokusebenza okudonsa amehlo ngokukhethekile.

I-Market Outlook

I-premium yomkhiqizo nezindleko zokukhiqiza yizinto ezimbili abakhiqizi abavame ukuzinaka. Ngokuphathelene nenani eliphelele ekukhiqizweni kwezolimo, izindleko zezibulala-zinambuzane azibali ingxenye enkulu, kodwa manje abalimi bokugcina banaka kakhulu ukuthi yimiphi imikhiqizo engonga isikhathi nezindleko zabasebenzi.

Ukunquma intengo yokuthengwa kwezinto zokusetshenziswa kuwumsebenzi obalulekile wabakhiqizi abangaphansi komfula ekulawuleni izindleko zokukhiqiza. Imakethe yezidakamizwa yasekuqaleni ibonakala obala, kodwa iyashintshashintsha ngokuhamba kwesikhathi. Uma abakhiqizi bokulungiselela besebenza eduze nabahlinzeki abangahlinzeka ngamanodi okuthenga angcono kanye nesigqi, kusho ukuthi bangakwazi ukonga ngempumelelo izindleko zokuthenga futhi bagxilise amandla abo nezinsiza ekubambeni iqhaza emqhudelwaneni ohlangothini lwamalungiselelo. Kule makethe yomhlaba wonke, Ukuhlanganisa isikhundla sayo emakethe "yevolumu" eyandayo.
Sizolinda futhi sibone ukuthi ubani ozophuma kulokhu kulwa futhi abe i-hit enkulu elandelayo ekulawuleni izinambuzane zelayisi.
