The management of terrestrial weed is of great concern for the scientific community as these weeds cause adverse effect in different ecosystems like forest, agriculture and urban. The widespread of these weeds by their adaptive capability and morphological advancement is difficult to control. Parthenium hysterophorous, Lantana camara, Saccharum spontaneum, Ageratum conyzoides are the weeds that...

Field experiments were conducted to evaluate the phytotoxicity of flazasulfuron on citrus species and efficacy on weeds when applied alone or in combination with other herbicides. Grapefruit was the most sensitive and tangerine was the least sensitive to flazasulfuron. Injury to grapefruit was 70% with the application of flazasulfuron at 0.20 kg a.i. ha at 60 DAT and was reduced (5%) when flaza...

The current interest in risks associated with classical biological control led us to review the literature to determine whether the introduction of multiple biological control agents has been more effective than the introduction of a single control agent. We analyzed 59 projects against weeds and 108 projects against insect pests. Establishment of control agents was significantly higher in sing...

BACKGROUND Rice-duck cultivation is the essence of Chinese traditional agriculture. A scientific assessment of the mechanism and its capacity is of theoretical significance and practical value in improving modern agricultural technology. RESULTS The duck's secretions, excreta and their treading, pecking and predation decrease the occurrence of plant diseases, pests and weeds, enrich species d...

Palmer amaranth (Amaranthus palmeri) is known to be glyphosate-resistant and one of the most common and troublesome weeds in Arkansas cotton production. Glufosinate is known to provide good control of 1-4 inch Palmer amaranth, but control of larger weeds is erratic. The lack of control provided by glufosinate on large weeds may be caused by coverage issues. The objective of this study was to ev...

Weeds are a major threat to biodiversity globally degrading natural areas of high conservation value. But what are our attitudes about weeds and their management including weeds in national parks? Do we know what a weed is? Do we consider weeds a problem? Do we support their management? Are we unintentionally spreading weeds in parks? To answer these questions, we surveyed visitors entering a l...

now a day winter cover crops planting has been attended to reduce herbicide application. an experiment was carried out at the research farm of agriculture faculty, bu- ali sina, university, in 2009. the experiment was a randomized complete block design with three replications. the trial included of five treatments consists of no cover crop, rye, winter oilseed rape, barley and triticale. the re...

Aquatic weeds pose several problems in India. The canals of Chambal commanded area in Rajasthan and Madhya Pradesh and Bhakra-Nagal in Himachal Pradesh and Punjab have been greatly slowed by the aquatic weeds. Several irrigation and hydroelectric projects in the country like Tungabhadra project in Karnataka, Nagarjuna Sagar project in Andhra Pradesh and Kakki and Idikki reservoirs in Kerala are...
