Weed control sugar beet

Some important weed species ate in the same family as the crop plant, e.g. charlock in oilseed rape or fat hen in sugar beet. Weed control using herbicides is then often difficult as there is not enough selectivity in the herbicide activity to kill the weed without injuring the crop. 

The major crops for agrochemical use are cotton, rice, maize, vegetables and top fruit for insecticides small grain cereals, rice, vines and top fruit for fungicides, and maize, soybeans, small grain cereals, rice, industrial weed control, plantations and orchards for herbicides. Other crops that may be of interest include sugar beet, oil-seed rape, potatoes and citrus dependent upon your company s presence in these crops.

Uses selective pre-emergence herbicide to control annual grasses and broadleaf weeds in tomatoes, sugar beet, and tobacco. 

Uses pre-emergence and post-emergence herbicide to control annual grass weeds in peas, beans, sugar beet, lettuce, lucerne, clover, flax, sunflowers and lentils. 

Uses as pre- and post-emergence herbicide to control of annual broadleaf weeds in sugar-beet, fodder beet and beet root and also used in combination with other herbicides, etc. 

Use Systemic herbicide, treatment of tobacco plants, postharvest sprouting inhibitor, weed control, sugar content stabilizer in beets.

At high rates of 1.2-3.5 tons of B20,/ha, all three borates are used pre-and postemergence as total herbicides for soil sterilisation on non-crop sites. At these rates they are suitable also for the eradication of St. John s wort (Litzenberger et al., 1945) and poison ivy (Stodard, 1944). At lower rates of40-100 kg B20j/ha they can also be used for selective weed control in sugar beet and fodder b t (Crafts and Raynor, 1936 Wang and Klotz, 1938 Crafts et al., 1941). 

TCA is a preemergence herbicide used for the selective control of grass weeds in sugar beet, sugar cane, alfalfa, peas and some other crops at a rate of 15-30 kg active ingredient/ha. 

Unlike TCA, dalapon is also absorbed through the leaves. Its effect can be enhanced by the addition of surfactants. It is used for selective weed control in sugar cane, sugar beet, maize, potato and in orchards. 

Diethatyl ethyl is a selective preemergence herbicide, effective mainly for the control of grass weeds on moist soil at an application rate of 1.7-6.7 kg/ha. It is selective in sugar beet, cotton, maize, wheat, soybean and vegetable crops. Its acute oral LD,o for rats is 2318 mg/kg. 

Used postemergence in sugar beet and cereals it selectively kills monocotyle-donous weeds. It is particularly effective for the control of wild oats (Avena fatua) (Brown, 1958 Hopkins et al., 1958). 

It can be used for the selective control of mono- and dicotyledonous weeds in onion, sugar beet, flower gardens and nurseries. It is used in combination with cycluron and pyramin (Fischer, 1960). 

It can be used for selective and total weed control at a rate of 1-7 kg active ingredient/ha. Sugar beet is particularly tolerant to asulam. 

Pebulate is a preplanting herbicide for the control of grass and broad-leaved weeds. Like the other volatile thiocarbamates, it must be incorporated in the soil. It is tolerated by a wider range of crops than EPTC. It is used in sugar beet, tomatoes and transplanted tobacco at a rate of 4-6 kg active ingredient/ha. Its action lasts for... 

Of the aliphatic urea derivatives a single compound, dichloral urea (DCU), has attained some practical importance (King, 1950), combined with Pyramin it is used in Hungary for weed control in sugar beet. 

DCU is a soil herbicide used at rates of 2-50 kg active ingredient/ha for preemergence treatment in sugar beet, cotton, oil flax, potato, carrots and medicinal herb cultures. In Hungary it is used in combination with Pyramin for weed control in sugar beet (Ubrizsy and Gimesi, 1969). 

Cycluron is generally used in a 3 2 combination with chlorbufam (1-methyl-prop-2-yn-yl-N-(3-chIorophenyl)carbamate) for weed control in sugar beet at 2-15 1/ha (Alipur , BASF). It is not recommended in monogermical sugar beet sowings because the plant can be damaged. 

Metamitron is a selective pre- and postemergence herbicide particularly suitable for selective weed control in sugar beet and red beet. The herbicide can be used very safely at a rate of 2.8-7.0 kg active ingredient/ha in all stages of development. It is...
