  • Chemical control gives excellent results: pre-emergence application of, for example, linuron or diuron with subsequent application of shielded sprays of paraquat, has proved successful.

    Chapter 11

  • For optimum yields yams must be kept free from weeds, at least for the first three months of growth, and the following herbicides have been used successfully: diuron 2.6 kg/ha, together with TCA at 4.4 kg/ha, and atrazine at 1. 5-2.9 kg/ha.

    Chapter 37

  • Regular weeding is necessary; hand-weeding is commonly practiced but nitrofen and diuron have proved to be effective in weed control without damaging the crop.

    Chapter 27

  • Pre-emergence applications of 2,4-D, MCPA, monuron and diuron at the rate of 1.7 kg/ha have been recommended for weed control.

    Chapter 10

  • Chemical herbicides are becoming increasingly used in the more sophisticated areas; pre-emergence herbicides include prometryn, diuron and nitrofen.

    Chapter 32

  • The application of the pre-emergence herbicide diuron at 1.6 kg/ha has been recommended; other effective herbicides are atrazine, prometryn and ametryn.

    Chapter 31

  • Simazine, diuron, and diphenamid may take even longer.

    Chapter 10

  • The discovery comes as the national chemical regulator, the Australian Pesticides and Veterinary Medicines Authority APVMA, considers whether to allow the continued use of diuron.
