Common water-plantain (Alisma plantago-aquatica L.), arrowhead (Sagitaria trifolia L.) and Echinochloa spp. (L.) are among the most important damaging weeds of rice paddies. In this research, Curvularia lunata (Waker) Boedijn was isolated from the said weeds. Then, its effect in different growth stages, i.e. seed, 2-3 leaf stage (seedling) and also in greenhouse conditions was examined in Alism...

Prevention and/or protection against chemical carcinogens by phytochemicals present in extensively consumed glucosinolate-containing cruciferous vegetables is of great of interest, as they provide a safe and cost effective means of combating cancer. Extensive epidemiological studies revealed repeatedly an inverse relationship between cruciferous vegetable consumption and the incidence of cancer...

FOREWORD The impact of environmental weeds on the natural environment is an area that has been little studied in Australia. More often than not, impact is assumed rather than quantified. If the impact of environmental weeds on nature conservation values is not quantitatively assessed before a control program is begun, valuable resources can be wasted. For instance, how would it be possible to d...

The most pervasive and harmful illness is cruciferous black spot disease. This disease starts to show symptoms as soon the seed emerges from soil continues all through growth season. In regions designated for seeds, cabbages left storage, areas planted human consumption, seen. Alternaria mostly affects plants’ organs responsible generating it severely damages pods seeds. leaves bulbs of crucife...

Broad spectrum weed control is essential for successful lesquerella [Lesquerella fendleri (Gray) Wats., Brassicaceae] production. Weeds must be controlled during establishment and throughout the growing season. Lesquerella seedlings grow slowly following germination and emergence, and cannot compete well with most broadleaf and grass weeds. Weed competition is particularly critical prior to clo...

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...

Yang, C.-C., Prasher, S.O., Landry, J.-A., Ramaswamy, H.S. and DiTommaso. 2000. Application of artificial neural networks in image recognition and classification of crop and weeds. Can. Agric. Eng. 42:147-152. The objective of this study was to develop a backpropagation artificial neural network (ANN) model that could distinguish young corn plants from weeds. Although only the colour indices as...

Development of an autonomous weeding machine requires a vision system capable of detecting and locating the position of the crop. It is important for the vision system to be able to recognize the accurate position of the crop stem to be protected during weeding. Several shape features of corn plants and common weed species in the location were extracted by means of morphological operations. Eff...
