Ngizokhuluma kancane ngalesi sifo uqobo. I-Powdery mildew inemvelo yokukhunta. I-ejenti ye-causative yi-fungi ehlukahlukene, emasikweni ahlukene inayo yayo. Kodwa ama-currants nama-gooseberry athinteka ezinhlobonhlobo ezifanayo - Sphaerotheca mors-uvae.
Umbala omhlophe, oqala ukubonakala emaqabungeni, uthwebula ezinye izingxenye zesitshalo. Uma ungalwa nayo, izithelo zimbozwa ngokuhamba kwesikhathi. Lokhu kuzokuphuca okungenani ingxenye yesivuno, futhi uma icala lisebenza, yilokho kuphela.
Ungabhekana kanjani ne-powdery isikhutha ku-gooseberries kanye nama-currants
Kunezindlela eziningi zokubhekana nalesi sishayo: kusuka ezindleleni ezithandwayo kuya kwezamakhemikhali.
Konke kuya ngokuthi ukuphatha ukucubungula amatshanyana njalo emavikini amabili, uma kunjalo, ke awudingi i-chemistry.
Ngizwe ukuthi bavame ukusebenzisa amanzi ashisayo (+90 ° C), bafaka wonke amahlahla nawo ekuqaleni kuka-Ephreli. Angizange ngiyivivinye le ndlela ngokwami, kunzima ukuphatha amanzi abilisiwe ekhaya. Futhi ngisebenzisa ukumfaka kumlotha (ngifaka i-1 kg kumalitha ayi-10 amanzi bese ngiwushiya izinsuku ezi-5, kwesinye isikhathi ngiyivuselele. Ngithululela isithako endaweni yesifutho.) Endleleni yokwenza i-ejenti "inamathele" ibe ngcono, engeza insipho encane ekutheleleni. Musa ukubamba isixazululo isikhathi eside, iyalahlekelwa izakhiwo zabo.
Enye indlela: sebenzisa i-mullein noma umquba. Ukuze wenze lokhu, udinga ukuthatha into eyodwa bese uyihluza ngamanzi i-1: 10, ugcizelele amahora ama-4, bese ufafaza zonke izihlahla. Kungcono ukukwenza lokhu ekuseni noma kusihlwa sezulu esifudumele, hhayi esinethayo.
Uma ungenaso isikhathi sokunakekelwa okujwayelekile, sebenzisa amakhemikhali (i-iron sulfate, i-colloidal sulfure).
Izindlela zokuvimbela izifo
Kodwa kungcono ukungavumeli isifo esinjalo. Ukuze wenze lokhu:
- Musa ukutshala izihlahla endaweni enomthunzi.
- Musa ukukhulisa ukutshala kwakho.
- Zama ukugcina ama-currant bush kude nama-gooseberries.
- Musa overdo it nge nitrogen.
- Yondla ngomanyolo we-phosphorus-potassium.
Okungcono nokho, izinhlobo zezitshalo ezingamelana nezifo. Isibonelo:
- ugqumugqumu - Kolobok, amagilebhisi e-Ural, eKuibyshevsky, eHarlequin;
- i-blackcurrant - iBinar, iBagheera, iparele emnyama, iMoscow;
- i-currant emhlophe - iBoulogne, isiDashi;
- i-currant ebomvu - iBoulogne, iRed Cross.
