Izifo zamagqabi ze-Corn Gaf ziqala ukubakho. La manyathelo alandelayo anokuthatyathwa ekuthinteleni nolawulo:
1.Khetha izinto ezinganyangekiyo.
2.Remomove intwana yenkwenkwe evela kwintsimi, iphuma ngokunzulu, kwaye ingcwabe pathoglens.
3.Ulawulo lwasesikolweni lwentsimi, ukwanda kwexesha lokutyala ngexesha elifanelekileyo, ukwandisa ukusetyenziswa kwesichumisi esiphilayo, ukunkcenkceshela okufanelekileyo, ukunkcenkceshela ngexesha elifanelekileyo, ukwandisa ukusetyenziswa kwemvula kunye ne-phossium yesichumisi kunye ne-potassium. Ukongeza, akukho phunga lokulima kunye nokuqhubeka nokunyuka kuya kwandisa ukwenzeka kwezifo
.
1, Igqabi legqabi
Ukuhanjiswa kwePathogen kunye neeMeko ze-ONSET:
I-pathogen yezifo zegqabi lombona ngokwamasalela ngokuncamathisela i-hyphae okanye i-condium ukuya kwizicubu ezinesifo. Ukuxhaphaka kwesifo samagqabantshintshi sombona akuhambelani kuphela kwesi sifo ukuxhathisa iintlobo zemibona, kodwa zinxulumene ngokusondeleyo kwiimeko zokusingqongileyo. Xa iqondo lobushushu lifikelela kwi-20 ℃ -25 ℃ kunye nokufuma okuzalwa kufikelela ngaphezulu kwe-90%, kuyingenelo kuphuhliso lwezifo. Ukuba icace gca emva kweentsuku ezininzi ezilandelelanayo, inokubangela ukuqhambuka kwe-vitiligo. Ukongeza, ukucoca ngequbuliso kwiintsuku zenkungu kunokukhokelela ekuphuhlisweni kwe-Macular Degeneration.
Uthintelo kunye noLawulo:
I-fungicides efana ne-AzoxystRobin kunye ne-propiconabane azoxystrobin inokusetyenziselwa ukuthintela nokulawula isifo segqabi le-Corn.
Ukuba ixesha lokukhula kombona lifike emva kwexesha, isichumisi segqabi le-monopotasphate phosphate yokupasa kwangoko linokongezwa kwi-fungicide kwaye isetyenziswe ngaxeshanye.
I-2, isifo sendawo emdaka
Ekwenzeka kumagqabi enkozo, amagqabi amagqabi, kunye neziqu, kuqala kwenzeka kwincam yamagqabi aphezulu, ezona ndawo zininzi zebala, zihlala zigcwele kwimigca. Ekuqaleni, yindawo encinci etyhefu emdaka okanye ebomvu emdaka, kunye nezifo ezijikelezayo ukuba zisetyhula okanye i-elliptical ukuya kwilayini. Izicubu zegqabi kufutshane neprotrusion zihlala zibomvu, kwaye amabala amancinci amancinci ahlanganisana. Kwiimeko ezinzima, amacandelo aliqela okanye onke amagqabi agutyungelwe ngamabala esifo, kwaye amabala amakhulu ansundu avele kwi-sheafs kunye namathambo esi sifo, i-theindidel yendawo enesifo egudileyo, amagqabi aselula yayikwimeko efileyo, kunye nomgubo onsundu (i-sporangium ye-pathogen) yasasazeka. Amagqabi anesifo aqhekezwe, kwaye amagqabi amagqabi kunye nebhanti ye-vascular alisa njengeefilim. Ukuba amaqondo obushushu aphezulu, umswakama uphakame, kwaye zininzi iintsuku zemvula ngoJulayi nango-Agasti. Kuyingenelo ekuqalekeni kwesi sifo. Kwiindawo ezinomgangatho womhlaba ohlukumelayo, amagqabi ajikaphule kwaye izifo zenzeka nzulu. Kwiindawo ezinomhlaba ophakamileyo wokuchuma, i-Corn yeyaba, amagqabi aluhlaza, kwaye izifo zinobulali okanye zingabikho. Ngokubanzi, esi sifo sithambekele ukuba senzekile xa kukho amagqabi angama-8-10 kwingqolowa, kwaye ngokubanzi akwenzeki emva kwamagqabi ali-12 kwi-CORN.
Uthintelo kunye noLawulo:
Uthintelo lwakuqala Isifo seSport Brown. I-PyrazolitidinoxREN, enokuphucula ugqirha ukumelana nesityalo ngokwawo.
, Ukuvela kwendawo emdaka kunye nezinye izifo ezivelelayo zinokulawulwa ngamaxesha angama-2500 kwi-25% ye-Pyrazolinoxinon, enokuphucula uxinzelelo lwetyala ngokwalo.
I-Anthrax ye-Anthrax
Ukudluliselwa kwePathogen: Inokudluliselwa ngokuhamba komoya kunye nembewu, kodwa ngokubanzi ireyithi yophethe imbewu iphantsi, ikakhulu ngenxa yokuba i-pathogen sporesings emva kokuhamba komoya kunye nemvula yosulelo. Amabala esifo anokubonwa kwiintsuku ezingama-4 ukuya kweli-10 emva kokuba amagqabi asulelekile, kwaye i-Condiim iveliswa.
Ulawulo lwekhemikhali: Ukuba kukho isifo, kwaye kukho imeko enkulu, kuyimfuneko ukutshiseka ngexesha, kwaye ngaphambi kokusetyenziswa kwechiza kangangoko kunokwenzeka, I-Pyrimidin, iSiloryCetin, iPyrazole Ether, njl.
