Efeito de fosfito de potassio e de fungicidas no controle da cercosporiose (
Cercospora beticola) da beterraba.
Reaction to
Cercospora leaf spot and leaf blight (Xanthomonas sesami) was somewhat similar among most of the genotypes with a mean of about 4.0 on 0-9 scale.
Selected rates of pyraclostrobin have superior activity against the peanut leafspots, caused by
Cercospora arachidicola and C.
and
Cercospora kikuchii was observed in the treatments in which fungicide was not used along the storage period (Table 3).
Brown eye spot (BE) caused by the fungus
Cercospora coffeicola Berkeley & Cooke, is one of the main diseases of coffee trees (Coffea arabica L.), causing reduced yield and quality of the beverage (LIMA et al., 2012).
The insects that may attack beets are flea beetles, leaf miners, aphids,
Cercospora leaf spot, scab and root rot.
(2004) verificaram a atividade antifungica do extrato aquoso de Momordica charantia, ao inibir 35% o crescimento micelial de
Cercospora calendulae a 10.000 [micro][g.mL.sup.-1] em calendula (Calendula officinalis L.).
Inducao de resistencia em cafeeiro contra
Cercospora coffeicola por eliciadores abioticos e extratos vegetais [Induction of resistance in coffee plants against
Cercospora coffeicola using abiotic elicitors and plant extracts].
Cercospora parthenophilia, a leaf spot pathogen isolated from parthenium at Kurukshetra, has shown several characteristics that make it a potential biological control agent of this weed in India such as wide natural distribution; it sporulates well on Czapek dox agar (a simple and cheap culture medium), within ten days, and can thus be mass produced in a short time and at low cost; it has narrow host range and capable of limiting populations of the weed under experimental conditions [56].
