As a vector control program to control Chagas disease in Guatemala, residual spraying of Rhodnius prolixus and Triatoma dimidiata was performed, and its impact was measured in the department of Zacapa. In order to identify infested villages and determine the degree of infestation, a baseline entomological survey to identify municipalities infested with vectors followed by an additional vector s...

abstract to evaluate the effect of sowing date and weed interference on growth indices of red bean cultivars with different growth habit, a field experiment was carried out during the spring 2009 at university of zanjan as a factorial split plot on the basis of randomized complete block design, with three replications. main plots included factorial of three red bean cultivars (derakhshan (stand...

The paper presents the results of a 2016–2018 study to determine effect share components in mixture and harvest date on weed infestation yield mixtures field pea with spring triticale. Two factors were studied experiment: proportion mixture: – clean sowing 100%, triticale 75% + 25%, 50% 50%, 25% 75%; harvesting date: flowering stage (BBCH 65), flat green pod 79). obtained allow us conclude that...

The host suitability to Ditylenchus destructor of seven common weed species in peanut (Arachis hypogaea) fields in South Africa was determined. Based on the number of nematodes per root unit, white goosefoot (Chenopodium album), feathertop chloris (Chloris virgata), purple nutsedge (Cyperus rotundus), jimson weed (Datura stramonium), goose grass (Eleusine indica), khaki weed (Tagetes minuta), a...

Allelopathy and competition are components of plant-plant interactions, delimiting the level interference. Understanding this interaction has practical applications in agriculture. Crop cultivars possessing high allelopathic ability competitive traits themselves tools for sustainable weed management, enabling reduced use herbicides. Greenhouse field experiments were conducted to assess suppress...

Population models are particularly helpful for understanding long-term changes in the weed dynamics associated with integrated management (IWM) strategies. IWM practices controlling L. rigidum of high importance, mainly due to its widespread resistance that precludes chemical control as a single method. The objective this contribution is simulate different scenarios special emphasis on impact l...

The paper presents the results of research on biological and economic efficiency new herbicide Femida, OD (2,4 D-acid, 320 g/l 2-ethylhexyl ester + 4.2 chlorsulfuron) produced by Schelkovo Agrohim, Ltd., Russia. It’s established that with protection winter wheat at tillering stage in spring reduction infestation annual perennial weeds amounts to more than 85 %, particular, blind weed,

OBJECTIVE To assess the effectiveness of an integrated community based environmental management strategy to control Aedes aegypti, the vector of dengue, compared with a routine strategy. Design Cluster randomised trial. Setting Guantanamo, Cuba. Participants 32 circumscriptions (around 2000 inhabitants each). Interventions The circumscriptions were randomly allocated to control clusters (n=16) ...
