Abstract:

In the Great Lakes region of the United States, cherry growers are poised to re-adopt copper-based fungicides to manage cherry leaf spot disease (CLS), caused by Blumeriella jaapii. However, application of copper is often associated with leaf bronzing. In growth chamber experiments, bronzing was observed on foliage of tart cherry (Prunus cerasus ‘Montmorency’) seedlings 1 week following application of a copper-based fungicide, only when leaves were also exposed to nightly dew. In potted, 1-year-old trees outdoors, light-saturated rates of net CO2 assimilation (A) and stomatal conductance (gs)

Abstract:

The recent introduction and rapid spread of rust on daylilies, caused by Puccinia hemerocallidis, suggested a need for fungicide treatments that reduce urediniospore viability on plant surfaces. Twelve fungicides in seven chemical classes were evaluated in vitro for toxicity to urediniospores of rust fungi that occur on daylily (P. hemerocallidis), geranium P. pelargonii-zonalis), iris (P. iridis), oxalis (P. oxalis), mint (P. menthae), and Florida azalea (Pucciniastrum vaccinii).

Fungicidal activity persisted well in simulated rain experiments, despite the high rainfall amounts tested (40 mm in 2004 and 90 mm in 2005). However, most of the fungicides showed a significant reduction of disease control on fruit of ‘Fortune’ mandarin in the orchard after natural rain in 2004. Fruit growth rate was low and did not appear to play an important role in decline of fungicide residues. C

Abstract:

Disease management in organic tomato production poses one of the greatest challenges for organic producers in humid climates. Both organic and conventional tomato growers have relied on copper (Cu) fungicides to control many diseases, including Septoria lycopersici common in tomato production. Concerns have been raised regarding the use of Cu fungicides, because of their potential to cause plant damage and toxicity to beneficial organisms.

An experiment was conducted to assess the compatibility of the popular insecticides like spinosad, cypermethrin, imidacloprid and chlorantraniliprole as well as fungicides copper oxychloride, carbendazim and hexaconazole with native isolates of M. anisopliae (MC 2, MC 4, MC 7). Among the isolates, MC 2, MC 7 and MC 4 were found compatible with insecticides spinosad, imidacloprid and chlorantraniliprole as well as fungicide copper oxychloride. Isolates MC 2 and MC 7 exhibited highest growth with only 3.70 and 5.18 per cent inhibition in the PDA medium amended with highest dose of copper oxychlo

Abstract:

Cercospora leaf spot of olive (CLSO), caused by Pseudocercospora cladosporioides, is one of the most important foliar diseases of olives worldwide. This study aimed to evaluate the effect of a wide range of fungicides on mycelial growth and conidial germination of P. cladosporioides in vitro, and to evaluate the effect of several fungicides, application timings and management strategies (conservative and risky) to control CLSO under field conditions. Of the studied fungicides, strobilurin compounds and benomyl were the most effective active ingredients, followed by folpet, captan and maneb, in

Summary The use of wood preservatives based on copper, chromium and arsenic (CCA) has become restricted in several countries due to environmental concerns. As a consequence, several chromium and arsenic free preservatives based on fungicides, regarded as more environmentally acceptable, have been developed. Most of these preservatives have only been tested in the laboratory against pure cultures of basidiomycetes and their long term effectiveness in practice is in many cases unknown. The effectiveness of six different preservatives, representing different types and combinations of fungicides,

Basil downy mildew (BDM), caused by the fungus-like oomycete pathogen Peronospora belbahrii, has become a destructive disease of sweet basil (Ocimum basilicum). Without proper management, BDM can cause complete crop loss. Currently, there are no commercially available sweet basil cultivars with genetic resistance to BDM. Because BDM is a relatively new disease of basil in the United States, there are few currently registered conventional or organic fungicides labeled for its control. Fungicide efficacy trials were conducted in 2010 and 2011 at Rutgers Agricultural Research and Extension Center

The addition of the silicone-based L-77 surfactant to the Kocide suspension markedly increased the spread of the droplets on cuticles and increased

Application of a copper citrate formulation with high degree dissociation at a very low concentration (1%) was evaluated in field trials.

In western Colorado, Cytospora leucostoma is ubiquitous in peach orchards and has developed into a major limiting factor of peach production.

Bark injuries caused by cold and pruning in commercial orchard systems provide infection courts that, in suitable environment conditions, can lead to many successful fungal infections. Preventive fungicide control is an integral component of management in tree fruit production. Eighteen fungicides were tested at selected label d
