What do you spray on sorghum?
Other herbicides such as 2,4-D, dicamba (Clarity), prosulfuron (Peak), bromoxynil (Buctril) and Huskie are also effective postemer- gence broadleaf herbicides for use in sorghum. Paraquat (Gramoxone Max) is labeled for post- directed use in larger grain sorghum to control escaped weeds.
Which post emergence herbicide used for sorghum?
Bromoxynil is a postemergence (POST) herbicide that is used for weed control in many crops and controls a broad spectrum of annual broadleaf weeds including Ipomoea spp., Sesbania exaltata (Raf.)
Will Poast kill sorghum?
2,4-D: 2,4-D is a broadleaf killer that has been around under many brand names for many years. It will not kill grasses. Grain sorghum infested with coffeeweed, ragweed, jimsonweed, morning glory or any other broadleaf qualifies for 2,4-D application.
Does glyphosate kill sorghum?
Unlike corn, no selective herbicides control johnsongrass in grain sorghum. Cultural management (such as crop rotation) or application of glyphosate using a rope-wick tool that touches only the weed and not the crop are the most common methods of controlling johnsongrass in grain sorghum.
How do you get rid of sorghum?
Sorghum should always be planted into a weed-free seedbed. The addition of a dicamba product or 2,4-D with glyphosate generally will control broadleaf and grass weeds effectively, provided an earlier burndown treatment has been applied in March or April.
Which is the root parasite of sorghum?
3.1 Striga. Striga is a devastating parasitic weed in Africa and parts of Asia. A single recessive gene controls low Striga germination stimulant (lgs) activity, a well-known resistance mechanism in sorghum (Hess and Ejeta, 1992; Vogler et al., 1996).
How do you control weeds in sorghum?
Though most effective on small weeds, when necessary, growers can use Huskie as a rescue treatment on larger weeds. Growers can apply Huskie to sorghum plants up to 30 inches tall before flag leaf emergence. The addition of a low rate of atrazine plus an adjuvant provides the best control.
Can I spray sorghum with 2,4-D?
Drop nozzles are recommended once sorghum exceeds a height of 8 inches. The addition of surfactants and other adjuvants with Clarity or 2,4-D is not recommended because it tends to increase crop injury.
What are orobanche and Striga?
All species of Orobanche and most Striga are obligate parasites-they will not develop at all without a host. Facultative parasites such as most of the parasitic species in the Scrophulariaceae are not nutritionally dependent on a host plant but they are invariably attached to one in nature.
What kind of weeds can Simazine be used for?
Simazine controls a wide range of annual and perennial weed seedlings and, depending on dosage and timing, also controls rosettes of winter annual weeds such as hawksbeard and horseweed (Ryan, 1968). Simazine is an important weed control tool in cherry (Gilbert et al., 1965; Anderson, 1989) and in apricot.
When was Simazine approved for use in corn?
Based on these expanded data, simazine was approved by the US Food and Drug Administration (USFDA) and US Department of Agricultural (USDA) for use in corn in 1958. Simazine has a broad spectrum of weed control in corn and a wide range of other crops.
Which is the best herbicide for grain sorghum?
There are preemergence as well as postemergence herbicides available for this crop. Early treatment provides the best control of broadleaved weeds with crop stage also being a critical factor for some postemergence treatments. Grain sorghum works well in no-till systems.
Is it safe to eat food with Simazine in it?
Compared with other notable sources, it appears that food is not a significant source of exposure to atrazine, simazine, or their dealkylated metabolites. Food appears to contain mostly the nonchlorinated metabolites, which seem to be less hazardous than the chlorinated degradation products.
