Parasitic weeds of the households Cuscutaceae, Orobanchaceae and Scrophulariaceae are thought of to be one of the significant difficulties dealing with agriculture within the Tropics and Subtropics. within the final many years, huge, immense efforts were made and good fortune accomplished by means of scientists world wide in gaining a greater realizing in their biology and ecology in addition to of regulate tools. in spite of the fact that, no vast aid of infestation has been completed some time past and keep watch over options particular to different parasites, plants and farming structures has to be additional constructed or tailored and realised between a much broader farming inhabitants with appropriate extension tools. This `Technical guide' offers updated methodologies for varied elements of study and extension on the topic of parasitic weed species of the genera Striga, Alectra, Orobanche and Cuscuta. It has the purpose to aid scientists and extension employees of overseas and nationwide examine and extension institutes and universities, who're both new to the topic or plan to use additional innovations they aren't but customary with.

Meetings on technical and engineering ceramics are held with expanding frequency, having develop into stylish as the capability of ceramics in ecocnomic development industries is an pressing topic of substantial debate and dialogue. eastern predictions are that the industry price of ceramics will develop 10 at approximately 10% every year to arrive not less than $10 by way of the tip of the century.
This quantity is a part of the Ceramic Engineering and technology continuing (CESP) series. This sequence includes a number of papers facing concerns in either conventional ceramics (i. e. , glass, whitewares, refractories, and porcelain tooth) and complex ceramics. subject matters lined within the zone of complicated ceramic comprise bioceramics, nanomaterials, composites, strong oxide gasoline cells, mechanical homes and structural layout, complex ceramic coatings, ceramic armor, porous ceramics, and extra.

Has also been shown to be very useful in the analysis of farming systems with regard to parasitic weeds. • Depending on the culture and ethnic groups women in agricultural households are responsible for different agricultural activities and crops. Therefore, women farmers should also be interviewed. LITERATURE Bengaly MP, T Defoer & WA Stoop 1996.

It includes the preparation of the survey (several days), the survey itself ( 15 to 30 min per field plus transport from field to field), and the time for the evaluation (days or several weeks according to number of samples and extent of analysis). PROCEDURE r:ir r:ir r:ir r:ir Randomized selection of fields, approx. every 5 to 10 km along roads. Use not only main roads! Select only fields were weed control, especially the weeding of parasitic weeds, has not yet been done by farmers. Give preference to fields where the crop has already reached the reproductive stage in order to include also late emerging parasites.
Participatory methods, such as informal qualitative interviews and group discussions, drawing of maps and transects, ranking and scoring, etc. has also been shown to be very useful in the analysis of farming systems with regard to parasitic weeds. • Depending on the culture and ethnic groups women in agricultural households are responsible for different agricultural activities and crops. Therefore, women farmers should also be interviewed. LITERATURE Bengaly MP, T Defoer & WA Stoop 1996. On-farm studies of Striga in South Mali: Contributions of a farmer participatory approach.
