    Notizen: As was described in a previous publication, the influence of a number og herbicides and herbicide mixtures which are being used for the post-emergence control of weeds in maize on the Transvaal Highveld, have been tested for their efficiency in the control of problem weeds. Both the percentage mortality and percentage dry mass difference between the test plants and the controls 10 days after application of the respective herbicides were used as bioassay methods. Datura stramonium L. was very susceptible to most of the herbicidal treatments up to the nine-leaf stage. The reason why it is considered a problem weed should perhaps be sought in the erratic germination of its seeds over a number of years, thus evading common practices of weed control.

    Notizen: A physical method is established for determining the population in the soil of viable seeds of the parasitic genera Alectra and Striga. Microscopic observation enables seeds of the two genera to be distinguished but it was not always possible to distinguish species within each genus. Correlation of the seed count with number of plants of these parasites was examined and factors lending to obscure correlation discussed.

    Notizen: A number of herbicides and herbicide mixtures which are being used for the post-emergence control of weeds in maize on the Transvaal Highveld, have been tested for their efficiency in the control of problem weeds. The evaluation was done under standardized conditions. The influence of the herbicides on the plants was evaluated by using the following bioassay methods: percentage mortality and the percentage dry mass difference between the test plants and the control 10 days after treatment.Recommendations are made as to which herbicides could be used most effectively on problem weeds post-emergence in maize fields. The developmental stage (age) at which each herbicide is most effective, has been determined.
