Definitions

  • Orobanche is a winter weed species first described in 1753 in Europe. This is a significant weed affecting the yield of many winter crops. Several strategies have been employed against orobanche species of weeds but few have been proved effective. Orobanche infests a locus by forming a pool of seeds in the soil. A control program aimed at controlling orobanche must target this seed pool within the soil. A simulation model by Kebreab and Murdoch, 2001 predicted that sustainable control of orobanche weed species must aim at reducing the seed pool to below 2000 seeds per square metre.
  • Fumigation is one such approach, which aims to eliminate the seed pool.
  • Some fumigants known for the control of orobanche weed species include methyl bromide, metham sodium, methyl iodide, 1,3-dichloropropene dazomet and ethylene dibromide.
  • these fumigants are known to be inferior in providing control of orobanche and their use is also becoming highly regulated.
  • Certain sulfonylureas have been employed for controlling broomrape. Chlorsulfuron was one such sulfonylurea, which not only provided incomplete control on single application but also delayed crop maturity (Kotula-Syka and Eleftherohorinos, 1991). Triasulfuron applied as a single foliar spray resulted into unacceptable damage to potatoes (Goldwasser et al., 2001). Rimsulfuron selectively controlled only O. ramosa, but it required repeated applications since its effect was temporary (Kleifeld et al., 1994).
  • Pyrazosulfuron-ethyl is pyrimidinylsulfonylurea herbicide having IUPAC name 5-[(4,6- dimethoxypyrimidin-2-ylcarbamoyl)sulfamoyl] - 1 -methylpyrazole-4-carboxylic acid and chemical structure as follows:
  • Pyrazosulfuron-ethyl is mainly absorbed by the root of weeds, and controls the synthesis of weed amino acid.

There is no recommendation in the state of the art towards the use of pyrazosulfuron ethyl for controlling winter weeds in winter crops.
  • Another object of the present invention is to provide for the selective control of winter weeds in winter crops.
