Abstract Pest regulation in agroforestry systems (AFS) is beginning to be well-recognized, but the mechanisms implied in the interaction network between the environment, pests and predators in AFS are still not well-described. The aim of this work is to understand how plant diversity associated with AFS regulates the coffee berry borer (CBB) taking into account a tripartite interaction network: pest–predator–environment. It further seeks to understand how farmers' management practices can modify...

Abstract Macadamia trees produce high quality nuts, and many Brazilian regions present ideal conditions for their cultivation. Aiming for financial returns during the first years of cultivation, macadamia have been grown as a coffee intercrop. Some Meloidogyne species are injurious to coffee trees, although information concerning the parasitism of these nematodes in macadamia nut trees is scarce. In this context, the aim of the present study was to evaluate the host status of seven varieties of ...

Abstract Botrytis blossom blight is an important disease of wild blueberries in Canada that causes over 20% yield losses annually. Four trials (2 in each year) were set up in 2015 and 2016 to investigate the efficacy of biofungicides against Botrytis blossom blight in wild blueberry. Botector®, Fracture® and Serenade MAX® were evaluated alone and in rotation with Switch® and compared with a standard control program (Fontelis®, Switch®, and Pristine®). Three applications of each biofungicide were...

Abstract Management practices, such as leaf removal, can affect grape cluster architecture and the microclimate around the cluster, which influences the development of Botrytis bunch rot disease. The timing of leaf removal among five different phenological stages was investigated as a tool for managing grape cluster architecture-related variables and for managing Botrytis bunch rot of Sauvignon Blanc grapevines. A commercial vineyard located in Sao Joaquim municipality, in the highland region of...
Abstract In recent years, Spain has been the scenario of the largest production growth of persimmon worldwide. However, circular leaf spot of persimmon, caused by Plurivorosphaerella nawae, was responsible for causing severe yield and economic losses. This work studied the effect of spray volume rate, droplet size, and application timing on spray distribution and disease control efficacy for mancozeb, pyraclostrobin and difenoconazole applications. Also fungicide degradation dynamics on persimmo...

Abstract Ipomoea eriocarpa R. Br., an annual prostrate plant, is a troublesome weed species in the tropical and sub-tropical regions of Asia, Africa, and Australia. For a better understanding of the plant's ecology, a seed germination study was conducted in order to predict the weed's ability to increase its global distribution, as well as presenting suitable management strategies for combating its spread. Germination and emergence of I. eriocarpa were examined in order to investigate the impact...

Abstract Extensive grain crop production systems in the Flat inland Pampas mainly include soybean, double-crop wheat-soybean and maize in rotation. Due to difficult-to-control weed problems, farmers are tending to intensify the rotations in their fields by increasing the number of double crops or by including cover crops before the main crop. Land use intensification may be characterized using the intensification sequence index (ISI), which is the number of crops per year considering all crops s...

Abstract Colletotrichum spp is one of the major cosmopolitan phytopathogens that cause postharvest anthracnose in dragon fruits. The pathogen attacks fruits on the field, during long-distance transport, and cold storage, leading to shorter shelf life. Traditionally, the plants are sprayed with synthetic fungicides, which is a strategic approach to control diseases in general and anthracnose in particular for dragon fruit production. Due to the demand for safe storage methods for consumers and th...

Abstract Citrus are important fruit crops of high economic and ecological importance in southern Cameroon. Smallholders usually plant citrus in complex cocoa-based agroforests (CBAS). Health and productivity of citrus are generally jeopardized by a wide range of pests and diseases for which environmental conditions can be critical drivers. An assessment of the effects of two structural characteristics of CBAS on citrus tree decline (CTD) intensity and six pests and diseases that induce it was co...

Abstract Determining toxicity of insecticides to natural enemies is essential for integrated pest management (IPM) programs of armored scales. In our previous work, insecticides did not affect seasonal abundance of parasitoids and predators of scale insects when they were applied one-month before their peak of season activity. In contrast, when applied during periods of natural enemy activity, trees treated with the broad-spectrum insecticide bifenthrin had fewer parasitoids and predators than t...
