Weed control potatoes

Use Delaying sprouting of potatoes, weed control, thinning of peaches, etc. 

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. 

Anuebunwa, F.O. 2000. A bio-economic on-farm evaluation of the use of sweet potato for complementary weed control in a yam/maize/egusi/cassava intercrop in pigeon pea hedgerows in the rain forest belt of Nigeria. Biological Agriculture and Horticulture 18(2) 95-102. 

Trietazine, a C/-triazine, was discovered by Geigy in the 1950s. Like some other triazines, it showed selectivity in potatoes. Fisons, Ltd. in England developed the product. There were limited sales in England through Fisons, but due to better weed control candidates, trietazine production was discontinued. For several years, though, trietazine was used in Japan to control weeds in chrysanthemums. 

Uses herbicide to control broadleaf and grass weeds in corn, sugarcane, some citrus fruits, and in noncropland also used as pre-harvest and post-harvest dessicant in potatoes to control crop and weeds. 

Uses Technical diquat dibromide is more than 95% pure and forms white to yellow crystals. It is used to desiccate potato vines and seed crops, to control flowering of sugarcane, and for industrial and aquatic weed control. It is not residual (i.e., it does not leave any trace of herbicide on or in plants, soil, or water). Diquat dibromide is a nonselective, quick-acting herbicide and plant growth regulator, causing injury only to the parts of the plant to which it is applied. Diquat dibromide is referred to as a desiccant because it causes a leaf or entire plant to dry out quickly.

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. 

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). 

Their most important application besides their use in maize culture is weed control in cereals, sugar cane, cotton, banana, pineapple, potato, sunflower and vegetable crops. Owing to their low persistence, which is favourable for crop rotation, their use is quickly becoming more widespread than the chloroamine triazines. 

Ametryne can be used in orchards and for vine, citrus, forest, maize, sugar cane, banana and pineapple cultures. Prometryne is used in cotton, potato, sunflower, bean, pea and carrot crops methoprotryne and terbutryne can be used in these crops and in cereals. Desmetryne and MPMT are used in soybean and cabbage crops for selective weed control. 

The rate of application for general aquatic weed-control is 2-4 kg active ingredient/ha, for non-crop weed control 0.5 kg/ha, for defoliation (of potato, alfalfa, etc.) 0.5-1 kg/ha, and for desiccation (of rice, maize, sunflower, oil flax, etc.) 0.4-0.5 kg/ha. The permissible residue is 0.5-2 ppm. 

Sencor . [Bayer Miles/Ag] Metribuzin selecdve h icide fa weed control in potatoes, tomatoes, soybean, turf, etc. 

Commercially, the most important compound containing the 1,2,6 thiadiazine system is Bentazone 5, a well-known, highly active, and selective herbicide. It controls broadleaf and sage weeds and is important for weed control in soybeans, sweet potatoes, pepper, oats, and barley <1996JSH519>. The great preponderance of literature from this period has to do with the properties (biological, environmental, synergistic, etc.) of this material. 

A bright new star, a nova, named DDT had just burst brilliantly into the plant protection heavens. It was accompanied by some bright satellites the dithiocar-bamatesforplant disease control 2,4-Dfor weed control and DDfor nematodes. Crop plants have never been so free of pests since agriculture was established. In the leaf hopper areas of America, potatoes have never been so green in September. The yields were doubled, often quadrupled. ... 

Uses Selective herbicide used for preemergence broad-leaved weed control in potatoes, tomatoes, lucerne, raspberry and sugarcane, and postemergence weed corrtrol in beets. Also itsed for selective control of annual grasses. 

Uses Herbicide used to control broad-leaved and grass weeds in com, sugarcane, certain citms subtropical fmits (bananas, pineapple) and in noncropland. Preharvest and postharvest desiccant used in potatoes to control both crop and weeds. 

Uses The amine, ammoiuum salt or acetate ester is used as a contact herbicide for postemergence weed control in cereals, cotton, peas, beans, potatoes, pumpkins, soybeans and strawberries. 

Variety should not be underestimated as a method of weed control. Many varieties of the same crop have very different growth and/or leaf habits. Varieties should be chosen that produce a vigorous leaf canopy, such as Cara maincrop potato, which will help suppress weeds. Varieties with horizontal (lax) rather than vertical leaves... 

Potatoes are very competitive against weeds. Weed control is usually completely mechanised as speciahsed potato ridge cirltivators are available. The other option is to chain harrow the ridges, then re-ridge afterwards. These crrltivations are usually done just before crop emergence. 

Key words potatoes, sugar beet, quota, soil management, weed control, blight, rhizomania. 

There are very few products which can be used post-emergence in potatoes. Metribuzin can be applied to some crops and varieties, as can the foliar-acting herbicides, bentazone and rimsulfuron. Several graminicides are approved for grass weed control, e.g. cycloxydim and propaquizafop. 

Peas do not compete well with weeds and efficient weed control is essential to avoid yield loss. Pereimial weeds should be dealt with before planting and thistles, oilseed rape and groundkeeper potatoes can be a particular problem. Nettles and thistles can interfere with hand picking and, in machine-harvested crops, weeds can lead to crop rejection from the processor. Inter-row cultivations may be effective when the peas are between the second and fifth node growth stage.
