Impact of Application Rate and Treatment Interval on the Control of Entomosporium leaf spot, Daylily Rust, and Powdery Mildew on Container-Grown Nursery Crops With MilStop

چکیده
MilStop fungicide was recently registered for the control of a number of leaf spot and blight diseases, as well as powdery mildew on numerous annual, herbaceous, and woody ornamentals. The active ingredient in MilStop is potassium bicarbonate. MilStop is reported to have curative activity against powdery mildew and is also labeled for the control of diseases caused by fungi such as Alternaria , Cercospora , Diplodia, Entomosporium, Phomopsis, and Septoria when applied as a preventative treatment. For effective disease control, the label specifies that applications of 2.5 to 5.0 pounds of MilStop per acre should be made at weekly intervals. Specific information concerning the activity of MilStop against many leaf spot and blight diseases on woody ornamentals is not available.

Organic and synthetic fungicides compared for control of leaf spot diseases and powdery mildew on crapemyrtle and hydrangea
While consumers are interested in organic or biorational alternatives to synthetic fungicides for the control of diseases of ornamentals as well as vegetables and tree fruits in residential landscapes, relatively few field trials have been conducted to establish their performance against ornamentals diseases. Weekly applications of Armicarb® 100 (potassium bicarbonate) controlled powdery mildew...
متن کاملPercentage distribution of foliicolous fungi of Maharashtra, India with respect to their disease symptoms: a novel study
Fungal spores are continuously deposited on the leaf surfaces by wind impaction, sedimentation and rain wash-out from the atmosphere and splash-dispersal. They reside and act as asymptomatic mutualists, benign commensals or latent pathogens. A slight imbalance in this relation can lead to pathogenic phase of the fungi, resulting in a variety of symptoms on leaves viz. discoloration, blight, soo...
متن کاملThe Lr34 adult plant rust resistance gene provides seedling resistance in durum wheat without senescence
The hexaploid wheat (Triticum aestivum) adult plant resistance gene, Lr34/Yr18/Sr57/Pm38/Ltn1, provides broad-spectrum resistance to wheat leaf rust (Lr34), stripe rust (Yr18), stem rust (Sr57) and powdery mildew (Pm38) pathogens, and has remained effective in wheat crops for many decades. The partial resistance provided by this gene is only apparent in adult plants and not effective in field-g...

To investigate the effects of silicon on the growth characteristics and the reduction of the powdery mildew damage to Zinnia (Zinnia elegans Jacq. ʻMagellanʼ), an experiment was carried out as a factorial experiment in the form of a randomized complete block design with two factors including eight treatments and three replications. The first factor included silicon concentrations at four levels...

Powdery mildew, caused by Blumeria graminis f.sp tritici, known as a destructive disease of wheat worldwide that led to severe crop loss, annually. As chemical control is expensive and not ecologically safe, application of non-toxic chemicals to induce defense mechanism in plant host is desirable. In present study, induction of host resistance using chitosan on the expression of pathogenicity r...
