e2“At the 5-leaf stage, injury to wheat and barley occurred only when sprayed at 10,000 ppm, whereas an increase in the grain yield was obtained at 1,000 ppm of 2, 4–D acid equivalent (1 kg a.i./ha)”

- Intervention effect Concentrations of 1,000 and 10,000 ppm of 2,4-D sprayed at the 3-leaf stage significantly decreased wheat height and grain yield.
- Intervention effect Concentrations of 1,000 and 10,000 ppm of 2,4-D sprayed at the 3-leaf stage significantly decreased barley height and grain yield.
- Intervention effect Spraying 2,4-D at 10,000 ppm at the 5-leaf stage injured wheat.
- Intervention effect Spraying 2,4-D at 10,000 ppm at the 5-leaf stage injured barley.
- Intervention effect Spraying 2,4-D at 1,000 ppm (1 kg a.i./ha) at the 5-leaf stage increased barley grain yield.
- Intervention effect Pre-emergence atrazine and simazine at 2.5 kg a.i./ha significantly increased maize forage and grain yields compared with unweeded check plots.
- Observation Wheat, oats, vetch and sugar beet were injured when planted after triazine-treated maize.
- Observation Onions and soyabeans were tolerant when planted after triazine-treated maize.
- Intervention effect Pre-emergence sprays at 1 and 2 kg/ha of other herbicides were judged promising on maize.
- Intervention effect Pre-planting EPTC and pre-emergence pebulate at 2 kg/ha gave a slight increase in sugar beet root yield.
- Intervention effect BV–201 and BV–207 were phytotoxic to beet.
- Intervention effect Nitrofen, BV–201 and BV–207 at 1–2 kg/ha were judged promising on onions as pre-emergence and post-emergence sprays.
- Intervention effect DNOC and dinoseb at 1.5 kg/ha and ioxynil at 0.5 kg/ha applied post-emergence significantly increased onion yield over the check.
- Intervention effect These herbicides had no significant effect on onion bulb index, moisture content or total soluble solids.
