Banded leaf and sheath blight (BLSB), caused by the necrotrophic fungus Rhizoctonia solani, is a highly devastating disease in most maize and rice growing areas of the world. However, the molecular mechanisms of perceiving pathogen signals are poorly understood in hosts.

Among the last of the noxious weeds to he introduced into the Cape Colony was the Amarantus Weed, at one time called Alternanthera echinata by botanists, but now technically known as Alternanthera achyrantha.

Rhizoctonia solani is one of the most important soil borne plant pathogenic fungus of many agricultural and horticultural crops worldwide. The detailed analysis of sheath blight resistance at genetic, molecular, biochemical and functional levels is facilitated by development of effective and uniform inoculation techniques. The efficiency of R. solani infection plays a pivotal role in accurate evaluation of disease and screening of resistant cultivars. In the present study, an innovative technique for artificial inoculation of R. solani in rice was evaluated under field conditions using maize sand meal as inoculum type. Development of sheath blight disease symptoms was found to be effective and uniform in inoculated plots.

[Objective] The aim was to study the pathogenic ability and biocontrol effect of different pathogens to potato plants.[Method] The pathogenic ability of Rhizoctonia solani soybean and Rhizoctonia solani rice to potato plants were studied by using living body vaccination bacteria method,and then the effects of biological control bacteria to disease were also investigated by spraying bio-control bacteria to disease.[Result] Rhizoctonia solani soybean had stronger pathogenic ability to potato plant than Rhizoctonia solani rice,among them the disease indexes of Rhizoctonia solani rice to leaf and stem of potato were only 25% and 50%,respectively.Bacteria had certain control effect to Rhizoctonia solani soybean,and the inhibitory rate reached 88%.Meanwhile the mixed bacteria and actinomycete had obvious bio-control effect to Rhizoctonia solani soybean,and the inhibitory rate reached 90%.[Conclusion] The research provides theoretical basis for the cultivation of potato and the control of Phyllachora graminis.

The occurrence of weeds in water rice was surveyed in the Red River Delta, Vietnam during spring and summer rice-growing seasons in 1995 and 1996. Sixty different weeds from 19 plant families were recorded. The most important plant families as weeds of rice were Poaceae and Cyperaceae. The most important weed however was Rotala indica (Willd.) Koehne (Lythraceae) followed by Echinochloa crus-galli (L.) Beauv. and Cyperus difformis L. A brief comparison of this rice weed flora and those of Australia and California was made.

In 1997, a weed survey was conducted during July and August in fields of wheat, barley, oat, canola and flax in Manitoba. Field selection was based on a stratified-random sampling methodology using ecodistricts as strata. Species in the Poaceae family were most commonly observed in the survey, followed by species in the Polygonaceae, Asteraceae and Brassicaceae families. The six most abundant weed species were green foxtail [Setaria viridis (L.) Beauv.], wild oats (Avena fatua L.), wild buckwheat (Polygonum convolvulus L.), Canada thistle (Cirsium arvense L.), redroot pigweed (Amaranthus retroflexus L.) and wild mustard (Sinapis arvensis L.). The survey highlighted significant differences between ecoregions and between crops in residual weed infestations. The weed community in the Boreal Transition ecoregion was dominated by seven species, whereas fields in the Aspen Parkland and Lake Manitoba Plain ecoregions were dominated by two species and the Interlake Plain ecoregion was dominated by only one species. Although significant differences were found between the weed communities in crops, they were not as great as differences between ecoregions. The Manitoba residual weed community in 1997 was very similar to that reported for 1978–1981 and 1986, suggesting that the same species should remain a focus for weed management.
