Plastic UV reßective mulch (metalized mulch) and wheat straw mulch delayed colonizationbyBemisia argentifoliiBellows&Perring and the incidenceof aphid-borneviruses in zucchini squash. No insecticides were used in either mulch treatment. The mulches were compared with a preplant treatment of imidacloprid and an untreated, unmulched control. In 2000, yield ofmarketable fruit in the plastic and st...

the sugarcane yellow mite, oligonychus sacchari (mcgregor, 1942) is one of the most important pests of sugarcane. in this study, the acaricidal efficacy of four different acaricides including biomite ® , gc-mite ® , oberon ® and envidor ® was assessed under laboratory conditions at 28 ± 0.5ºc, 50 ± 5% rh and a photoperiod of 16:8 h (l:d). adults of o. sacchari were exposed to treated leaves of ...

in order to investigate the possibility of reducing herbicide usage in combination with plant density and planting pattern, a field experiment was designed in chenaran, khorasan razavi, on 2010. the experiment was split plot treatments based on rcbd with three replications in factorial arragement. the treatments included of 3 level of plant density (100000, 120000 and 140000 plants ha-1) and 2 ...

field experiment was conducted to assess the efficacy of wheat residues and different densities of sunflower in weed control during 2007 growing season. the experimental design was a randomized complete block with three replications. the experiment was set up in factorial arrangement, amount of 0, 1250, 2500, 3750, 5000 kg ha-1 of wheat residue and burning of residue (5000 kg ha-1) were the lev...

Intensive tillage, high fertiliser inputs, and plastic mulch on the soil surface are widely used by vegetable growers. A field investigation was carried out to quantify the impact of alternate land management and fertiliser practices designed to improve offsite water quality on the productivity of vegetable rotations within a sugarcane farming system in a coastal region of subtropical northeast...

mixing herbicides is an essential for weed management strategy of reduce herbicide using and reducing the risk of side-effects and costs of herbicides. therefore, to study the effect of clopyralid and glyphosate and their mixtures on acroptylon repense control, a field trial was conducted as split plot based on a completely randomized block design with 35 treatments (as dose-response arrangemen...

Environmental risks resulting from increasing application of herbicides have raised many concerns about human health and safety of agro ecosystems and environment. Hence, it is very important to find practical and effective methods for reducing the use of pesticides in environment as well as the increasing the efficiency of these compounds. Addition of adjuvants to spray solutions could be cons...

Moving towards sustainable agriculture implies exploring the interconnections between farming and the environment, and soil is a key component of sustainability. Mulching is one of the methods to protect and enhance the productivity of the soil. We studied here the effect of mulching applied to mandarin tree rows for weed control in two localities near Tortosa, Spain, to compare its performance...

Inadequate rainfall is a significant problem hindering the production of most crops in dryland regions. The current study was carried out to assess effect selected soil-water conserving interventions on soil moisture, growth, yield, quality, and profitability yellow passion fruit. experiment laid randomized complete block design (RCBD) at Kenyatta University (Kiambu County) Ugweri (Embu County)...
