Sencor

Overview

Post-Emergent Broadleaf Weed Control In Pulses


Sencor® is a proven broad-spectrum herbicide registered for broadleaf weed control in a wide range of crops, most notably chickpeas, field peas, lentils and potatoes.

Because of its Group 5 mode of action, Sencor helps manage and prevent Group 2-resistant broadleaf weeds including hemp-nettle, chickweed and wild mustard. A program utilizing both Edge®and Sencor can help manage weeds such as kochia and their Group 2- and 9-resistant biotypes. Sencor also provides control for all herbicide-tolerant volunteer canola and its convenient packaging means no triple rinsing or jugs to return. Sencor provides a great alternative to Group 2 products that are used heavily in pulses and helps prevent Group 2-resistant broadleaf weeds in a heavy pulse rotation.

Application Guidelines

Overview


  • Sencor® is a proven performer and when it comes to broad-spectrum weed control, it's reliable and cost-effective
  • The only post-emergent broadleaf weed control product registered in lentils, field peas and chickpeas
  • Residual activity provides control of flushing weeds
  • Convenient packaging means no triple rinsing or jugs to return
  • Sencor is a Group 5 herbicide that helps manage and prevent Group 2-resistant broadleaf weeds including, hemp-nettle, chickweed and wild mustard
  • Sencor provides a unique non-Group 2 broadleaf weed solution for your pulse crop
  • When used in a program with Edge®, the combination will help manage weeds such as kochia (resistant to Group 2 and 9 herbicides)
  • Controls all herbicide-tolerant volunteer canola

 

Rates – Pulse Crops
Sencor has different use rates depending on the crop. Please refer to product label for exact information regarding application.
Lentils
  • Single application: a 2.5 kg bag treats 22.5 acres at a rate of 111 g/ac.
  • Split application: a 2.5 kg bag treats 32-44 acres at a rate of 57-77 g/ac.

Chickpeas

(Desi & Kabuli types only)
  • Single application: a 2.5 kg bag treats 22.5 acres at a rate of 111 g/ac.
Field peas
  • Single application: a 2.5 kg bag treats 16.5-22.5 acres at a rate of 111 g/ac.
  • Split application: a 2.5 kg bag treats 32-44 acres at a rate of 57-77 g/ac.
  • Five 2.5 kg bags of Sencor Solupak plus three 10 L jugs of MCPA Na-salt treats 160 acres

 

Timing – Pulse Crops
Sencor has different timings depending on the crop. It can be applied pre-plant, pre-plant incorporated, pre-emergence or post-emergence. Please refer to product label for exact information regarding application.
Lentils
  • For lentils apply first application from cotyledon to the 2 leaf weed stage, with the second application when the second flush appears. Allow seven to 10 days between first and second application. Apply first application at a rate of 77 g/ac. and the second application at a rate of 55-77 g/ac.
  • For best results, apply Sencor when lentil vines are less than 6 in. long or are in the 3 to 5 node stage
  • Plant at a seed depth of 2 in. to decrease the risk of product leaching into the root zone; larger seeded lentils are less prone to injury than smaller seeded lentils (e.g., Laird vs. Milestone)
Chickpeas (Desi & Kabuli types only)
  • For best results, apply Sencor when chickpea vines are less than 2.5 in. high or are in the 1 to 3 node stage
  • Desi chickpea varieties are less tolerant than the Kabuli varieties, so care should be taken when applying Sencor Solupak
Field peas
  • For best results, apply Sencor with MCPA Na-salt when the vines are less than 6 in. long, or before the 6 node stage
  • Apply the first application at the 2 leaf weed stage and the second application at the second flush

 

Packaging
  • Five 2.5 kg bags of Sencor Solupak plus three 10 L jugs of MCPA = 160 acres

 

Water Volume
  • Ground – minimum 15 US gal./ac. (70 L/ac.)

 

Rainfastness
  • Six hours after application

 

Residue and Grazing

Do not:

  • Graze treated wheat or barley crop or feed treated crop to livestock within 30 days of application
  • Graze treated field peas, processing peas, chickpeas, lentils or feed treated crops to livestock within 70 days of application

 

Re-cropping Intervals

Sensitive crops for the year after Sencor application include: onions, celery, peppers, cole crops, lettuce and spinach, sugar beets, table beets and turnips, pumpkin and squash, cucumbers and melons, tobacco and non-triazine-tolerant canola (rapeseed).

Note: Most of the crops listed above apply to Eastern Canada.

 

Tips and Tricks


  • Apply Sencor as a broadcast spray mixed with a minimum of 15 US gal./ac. (57 L/ac.) of water – lower water volumes will increase the risk of leaf burn
  • Sencor should be mixed with water only and not with fertilizer solutions
  • Follow Sencor applications with a post-grass treatment such as Centurion® and allow four to five days between applications – if grassy weeds emerge first, apply Centurion followed by Sencor in four to five days
  • Better weed control performance can be attained with a split application of Sencor
  • Do not use on soils with less than 4% organic matter
  • Growers applying Sencor herbicide on soils with low organic matter levels (but greater than 4%) should reduce rates and apply Sencor in split applications
  • Do not apply Sencor if the short-term forecast calls for rain of two or more inches; applications followed by high precipitation can lead to leaching
  • Crop root uptake can show symptoms seven to 10 days later; this can lead to stand reduction and plant injury

Resistance Management

Where possible, rotate the use of Sencor® or other Group 5 herbicides with products from different herbicide groups that control the same weeds in the field.

Broadleaf weeds such as hemp-nettle, chickweed and wild mustard continue to become resistant to weed control products with Group 2 chemistry. A combination of Edge® and Sencor will help manage resistant populations of kochia. As a Group 5 herbicide, Sencor provides another mode of action in herbicide rotation strategies for these weeds and others that appear on the Sencor label. Sencor will also control all herbicide-tolerant volunteer canola.
