“Cracking” Time Again on Peanuts (Prostko)<\/a><\/h3>\n\n\n\n

Many peanut growers are in the field right now making “cracking” applications of paraquat (whether they really need it or not?<\/em>).\u00a0 I always get tons of questions about product use rates.\u00a0 Check out these pictures from earlier today.\u00a0 These are rates I have been testing for years and they work pretty much all the time (when applied to small weeds 1″-3″<\/em>).\u00a0 Higher rates and later applications, especially in dryland fields, can push a peanut plant’s paraquat tolerance to its limits.\u00a0<\/p>\n\n\n\n

A few other thoughts:<\/p>\n\n\n\n

1) If grower wants to use the 3 lb\/gal formulation of paraquat (i.e. Helmquat or Gramoxone 3SL), the normal application rate in these tank-mixtures is 8 oz\/A (0.1875 lb ai\/A).<\/p>\n\n\n\n

2) If a grower wants to use Basagran 4SL (bentazon) instead of Storm 4SL (bentazon + acifluorfen), I would suggest using 8 oz\/A of Basagran 4SL.<\/p>\n\n\n\n

3) If a grower wants to make his own Storm, I would suggest the combination of Ultra Blazer 2SL @ 16 oz\/A + Basagran 4SL @ 8 oz\/A.<\/p>\n\n\n\n

4) I am not a huge fan of using paraquat + Dual Magnum or any other Group 15 herbicide without some Basagran or Storm to cool it down some on the peanut plant.  <\/p>\n\n\n\n

5) No adjuvants are needed when Dual Magnum or Outlook are used (i.e. oil-based formulations<\/em>) but NIS @ 0.25% v\/v (1 qt\/100 gallons) is suggested when using Anthem Flex, Warrant, or Zidua.<\/p>\n\n\n\n

More on Peanut Weed Control- Prostko<\/strong><\/p>\n\n\n\n

Peanut growers will be making the decision to spray or not spray an early-postemergence (cracking<\/em>) herbicide.\u00a0 If the peanut field was clean at planting and a strong residual herbicide program was used (activated with moisture), it is very likely that a cracking spray will not be needed.\u00a0 See below (i.e. no weeds in my standard PRE program at 12 DAP):<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

My general recommendations for early-postemergence (cracking<\/em>) treatments in peanut are as follows:<\/p>\n\n\n\n

a) Either paraquat (2 lb\/gal) @ 12 oz\/A or paraquat (3 lb\/gal) @ 8 oz\/A + either Storm @ 16 oz\/A or Basagran @ 8 oz\/A + one Group 15 herbicide [either Anthem Flex @ 3 oz\/A or Dual Magnum @ 16 oz\/A or Outlook @ 12.8 oz\/A or Warrant @ 48 oz\/A or Zidua @ 2.5 oz\/A (liquid)]. <\/p>\n\n\n\n

Generally, I have no preference between the Group 15’s when my suggested PRE\/EPOST\/POST peanut weed control programs are followed.<\/u><\/em><\/strong><\/p>\n\n\n\n

b) Add NIS @ 0.25 v\/v when using Anthem Flex, Warrant, or Zidua.<\/p>\n\n\n\n

c) If need be, growers can make their own Storm (I call it Georgia Storm<\/em>), by tank-mixing Ultra Blazer (16 oz\/A) + Basagran (8 oz\/A). This is a slightly different rate than what is applied with current commercial Storm formulation @ 16 oz\/A (equivalent to Ultra Blazer @ 11 oz\/A + Basagran @ 11 oz\/A).<\/p>\n\n\n\n

d) Use at least 15 GPA and pressure\/nozzle configurations to produce medium to coarse droplets (236-403 microns).\u00a0 Medium\/coarse droplets are yellow and green on this chart.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

e) Excessive dust caused by dry weather and tractors driven at Warp Speed 10 will reduce the effectiveness of paraquat.\u00a0\u00a0<\/p>\n\n\n\n
