Cotton Crop

What weeds most affect cotton production in Australia?? In particular the Darling Downs QLD. If any one knows of a site then that would be great. I've tried searching for ages and I can't find anything useful. If you can think of any of the weeds names then that would also be very helpful.

The first two links are fact sheets with some key weeds listed for cotton in the Darling Downs (it does say dryland cotton), and the third has info about weed species in cotton. Good luck, hope it helps a bit. Another suggestion, maybe you could find a Qld Dept. of Primary Industries office in the Darling Downs region and ask them for help as they might know or know who to ask.

The overall crop size may be down this season, but cotton growers with full water have been achieving yields among their best ever as they ...

Can anyone tell me whether the cotton crop is good in dry or wet condition??

Successful cultivation of cotton requires a long frost-free period, plenty of sunshine and a moderate rainfall, usually from 600 to 1200mm (24 to 48 inches).

Soils usually need to be fairly heavy, though the level of nutrients does not need to be exceptional. In general, these conditions are met within the seasonally dry tropics and subtropics in the Northern and Southern hemispheres, but a large proportion of the cotton grown today is cultivated in areas with less rainfall that obtain the water from irrigation.

To suppress excessive
vegetative growth
mepiquat chloride (various
brands) 0.35 lb/gal
0.5 to 1 pt Base rate and timing on field conditions. Most consistent results occur when applied to cotton that is
at least 24 in. tall at early bloom (5 to 6 white blooms per 25 ft of row). A follow-up application may be
warranted 10 to 14 days later if excessive growth continues.
When early season conditions promote excessive prebloom growth, mepiquat chloride may be
applied at the rate of 0.125 to 0.25 pt beginning at match head square (first square 0.125 to 0.25 in. in
diameter). Repeat applications can be made when regrowth occurs. Follow label directions.
Mepiquat chloride will consistently suppress vegetative growth. Other benefits may include easier
scouting, better insecticide coverage, less boll rot, earlier maturity, easier defoliation, and more efficient
use of ground sprayers and low drum pickers. Yield response is inconsistent.
mepiquat pentaborate (Pentia) 0.82 lb/gal
4 to 24 fl oz
cyclanilid 1.4 lb/al
+
mepiquat chloride 0.73 lb/gal
(Reign SC)
2 to 2.5 fl oz Use the 2 fl oz rate if applied at match-head square and the 2.5 rate on applications following matchhead
square.
To stimulate boll opening
and enhance defoliation
ethephon
(Boll-D) 6 lb/gal
(Ethephon) 6 lb/gal
(Prep) 6 lb/gal
(Super Boll) 6 lb/gal
0.66 to 1.33 qt Use higher rate during cool weather.
Prep boll opener will accelerate boll opening and enhance the activity of defoliants. It will not stimulate
boll maturity. Micronaire may be reduced if Prep is applied to cotton that is less than 60 percent open.
Further more information, see Extension publication AG-417, Cotton Information, which is available at your county Cooperative Extension center.
GUIDE FOR USE OF DEFOLIANTS ON COTTON
K. L. EDMISTEN, Crop Science Department
Apply defoliants when at least 60 percent, preferably 70 to 75 percent, of the bolls are open and the remaining bolls expected to be
harvested are mature. A boll is mature enough for defoliation when it is too hard to be squeezed between thumb and fingers, when it
is too hard to be sliced with a sharp knife, and when the seed coats turn light brown. Apply defoliants in a volume of 12 to 25 GPA by
ground or at least 5 GPA by air. If a second application is needed, consult label for rates.

Per Acre Remarks
carfentrazone Aim (2 lb/gal) 1 to 1.5 oz We have limited experience with Aim in North Carolina. Aim, like other herbicidal defoliants, can
cause desiccation; however, the desiccation appears to be more transitory than that achieved with
some of the other herbicidal defoliants. Aim appears to desiccate mature morningglories very well,
and it does not seem like the addition of ethephon-type products is needed to improve morningglory
desiccaton. The label recommends a minimum of 10 gal per acre for ground applications and
the use of oil concentrate at 1% by volume (1 gal per 100 gal of spray solution). Do not use crop
oil concentrate with Aim in mixtures with CottonQuik. Aim can be tank mixed with other defoliant
products if boll opening or regrowth control is desired. Lower rates may be needed in defoliation
mixtures.
ethephon + cyclanilide Finish (6 lb/gal) 1.33 to 2 pt Use higher rates in cool weather. Finish is defoliant and boll opener. Finish also provides regrowth
control. Terminal regrowth control is stronger than basal regrowth control. Finish will provide
acceptable regrowth control in many situations. In situations where extended regrowth control is
needed (in the 20- to 28-day range), Dropp or Roundup would provide more acceptable regrowth
control. Finish performance may benefit from the addition of a low rate of a standard defoliant in
situations where cotton is actively growing with juvenile growth. Use compatibility agent when mixing
with Def 6 or Folex.
glyphosate Roundup 24 to 32 oz Based on limited trials in N.C., Roundup provides effective regrowth control. Roundup provides
very little defoliation and should be used in combination with a defoliant. Experience in N.C. is
limited to tank mixes with 1.5 pt of Def or Folex per acre. Although Roundup prevents regrowth, it
will not defoliate juvenile growth that may occur prior to defoliation. Roundup also provides some
weed control when defoliating weedy cotton. Roundup will not provide regrowth control on Roundup
Ready cotton.
mono (N,Nimethylalkyamine)
salt of endothall
Accelerate (0.52 l lb/gal) 1.0 to 1.5 pt Accelerate may be added to Def or Folex at 1.5 pt per acre to speed leaf drop by approximately
25 percent during the first few days of defoliant activity. The rate of leaf drop after 7 to 10 days has
generally not been improved with Accelerate. Always add Accelerate to organic phosphates (Def or
Folex) previously tank mixed with water.

pyraflufen-ethyl ET (0.2 lb/gal) 1.5 to 2.5 oz We have limited experience with ET in North Carolina. Like all herbicidal defoliants, ET can cause
desiccation, although the desiccation tends to be transitory compared to some herbicidal defoliants.
ET should help with desiccation of morningglory and other weeds listed on the herbicide label. ET
can be mixed with other harvest-aid materials to provide boll opening or regrowth control. Consult
the label for additive recommendations. In general, the use of a crop oil concentrate at 0.5% by
volume is recommended. Do not use crop oil concentrate with ET in mixtures with CottonQuik. Use
lower rates in warm weather.
N-phenyl-N,1,2,3-thiadiazol- Dropp (50% WP) 0.2 to 0.4 lb Dropp is very effective at regrowth suppression. However, the activity of Dropp is reduced a greater
5-ylurea Free Fall (50% WP) extent by cool weather than the activity of Def 6, Folex, or Harvade. Dropp requires the longest rainfree
period of any of the defoliants—24 hr. Follow label directions and safety precautions.
N-phenyl-N,1,2,3- Dropp Ultra (75% WP) 0.1 to 0.25 lb Dropp Ultra is a mixture of Dropp and Diuron. Dropp Ultra may cause desiccation under very hot
thiadiazol- 5-ylurea and conditions, especially with high humidity. The addition of other defoliants is not recommended
3-(3,4-dichlorophenyl)-1,1- except for Prep or generic ethephon products. The addition of crop oil concentrate may improve
dimethylurea performance in cooler weather. The addition of silicon surfactants is not recommended with Dropp
Ultra.
Ginstar (1.5 lb/gal) 0.4 to 1 pt Ginstar is a mixture of Dropp and Diuron with an emulsifier that makes it more likely to desiccate
than Dropp Ultra. Do not use Ginstar if temperatures are over 90o F. The addition of other defoliants
is not recommended except for Prep or generic ethephon products. Ginstar rates should not exceed
10 oz per acre in N.C. except under very adverse conditions.
1-aminomethanamide CottonQuik 1.75 to 3.5 qt Use higher rates in cool weather. The 2 qt rate is recommended for most situations. Use a low rate
dihydrogen tetraoxosulfate of a standard defoliant with CottonQuik unless the cotton is well cut-out with no juvenile growth.
and ethephon
sodiumcacodylate and Cacodylic acid (Quick 0.5 to 1.5 pt Tank mix Quick Pick with Def, Folex, Prep, or Harvade for best results. Avoid high rates in hot
dimethylarsinic acid Pick) 3.1 lb/gal weather as leaf desiccation may occur. Experience with Quick Pick in N.C. has been limited to cool
conditions. Follow label directions.
tributyl phosphorotrithioate Def 6 (6 lb/gal) 1.33 to 2 pt Use lower range of rates if crop is well matured as indicated by yellow- or red-tinged foliage or when
temperatures are warm. Use higher recommended rates when plants are still green and actively
growing or in dry weather or cool weather; needs a 2-hr rain-free period. Follow label directions and
safety precautions.
tributyl phosphorotrithioite Folex (6 lb/gal) 1.5 to 2 pt See above remarks.
2,3-dihydro-5,6-dimethyl 1,4 Harvade (5 lb/gal) 0.5 pt The addition of 1 pt of crop oil concentrate per acre is necessary for acceptable results. Rainfall
dithiin 1,1,4,4-tetraoxide within 6 hr may reduce activity. Results similar to those from Def 6 or Folex. Follow label directions
and safety precautions.

im writing a paper about how cotton changed the south. And i know that back in the 1800s cotton was the number one cash crop, but how?

Well, I[m not sure what you are looking for but it was easy to grow and after the 1793 invention of the cotton gin it could be prepared for sale overseas very easily therefore it sold in great quantity. By 1860 cotton sales accounted for nearly 75% of all exported goods sold from the South.

Explain the history of the development of cotton as the major crop in the South. Futhermore, detail how this development led to the growth of slavery.

Cotton had originated in the south because it grew well in the southern climate. However, harvesting the cotton and removing the intricately weaved seeds from its fibers was very arduous work and come the 1800's the south was thinking of switching its economy from being agriculturally dependent on cotton to a industrial society such as that of the North. They had even agreed to ending the slave trade with Africa in 1808 because they believed they would no longer need slaves in a industrialized society. However, when Eli Whitney invented the cotton gin it made cotton production much simpler and a single slave could harvest 100 pounds of King cotton a day instead of the 20 pounds a day they used to be able to. Suddenly southern plantation owners realized that they didn't need to get rid of cotton production. They were becoming richer than ever before and textile companies in both England and the North were eager to buy their product. Cotton became the highest demanded product in the known world. It was making the south rich and bringing in the majority of their economic value. The slave trade had already ended however and southern plantation owners needed to find an alternate source of slaves. Thus, they begun to buy slave "breeders". They would breed slaves and then use the children as workers on their plantations or would take them from their families and sell them. The south soon noted female slaves as more valuable than male slaves because they could produce more slaves. The more slaves a person had the more rich they were. Each slave was worth around $1,500. That was a very high amount back then. Their value was placed in the income their work would bring in, or the price they could be sold for to another plantation. The demand for slaves increased as the demand for cotton grew in the North and in England and as southerners desire for wealth grew.
