GRAIN SORGHUM (MILO) - CONVENTIONAL TILLAGE - MEDIUM (PREEMERGENCE SURFACE)
INTRRO Preemergent Herbicide is recommended for control of yellow nutsedge and the annual grasses and broadleaf weeds listed in the “WEEDS CONTROLLED” section of the label. This product may be applied either as a surface application before or after planting or shallowly incorporated prior to planting to blend the herbicide treatment into the upper 1 to 2 inches of soil. The seedbed should be fine, firm and free of clods when tillage is performed. Read and carefully observe precautionary statements and all other information appearing on the labeling of all products used in mixtures and sequential treatments.
Do not flood irrigate following application of this product or tank-mixtures.
This product will not control emerged seedlings.
Do not apply when conditions favor drift.
Applications, which are not consistent with the label, may result in injury to persons, animals or crops, or other unintended consequences. Keep container closed to prevent spills and contamination.
Flush sprayer with clean water after use.
SOIL TEXTURAL GROUP
Applicators must evaluate soil and weed conditions carefully to ensure that they choose the lowest effective label rate.
The use rates of this product and the other herbicides labeled for use in tank mixtures with this product generally vary with soil texture. Unless soil texture is specifically named, rate tables throughout the label refer to only three soil textural groups: coarse, medium and fine.
Ground Broadcast Treatment—For application into CONVENTIONAL TILLAGE SYSTEMS, apply this product and the labeled tank-mixtures in 10 or more gallons of solution per acre using broadcast boom equipment.
For application into CONSERVATION OR MINIMUM TILLAGE SYSTEMS, apply in 10 to 20 gallons of water or 10 to 60 gallons of nitrogen solution per acre when adding a Roundup agricultural herbicide or 2,4-D to the mix. Apply in 20 to 60 gallons of water or nitrogen solution when adding Gramoxone herbicide to the mix. The carrier may be either water or sprayable fluid fertilizer as specified for the crop to be treated in the “DIRECTIONS FOR USE” section of the label. Do not apply during periods of gusty winds, when winds are in excess of 15 miles per hour or when other conditions favoring drift exist.
Band Treatment—Apply a broadcast equivalent rate and volume per acre.
APPLICATION TIMING AND METHODS
Early Preplant Surface—Some labeled tank-mixtures of this product may be applied in no-till and other conservation tillage systems before weeds emerge and up to 45 days before planting certain crops. Split applications can be made 30 to 45 days prior to planting, with 60 percent of the broadcast rate applied initially and the remaining 40 percent applied at planting. Applications made less than 30 days prior to planting can be made either as a split or as a single application. Refer to the individual crop to determine if early preplant application is recommended. If weeds are present at the time of application, apply this product in tank-mixtures with an appropriate contact herbicide. Observe directions for use, precautions and restrictions on the label of the contact herbicide. During the planting operation, be careful not to move untreated soil to the surface or move treated soil out of the row, as weed control may be reduced.
Preplant Incorporation—This product and many of the labeled tank mixtures may be mixed into the soil using shallow incorporation equipment any time within 7 days prior to planting. Refer to the crop to be treated in the “DIRECTIONS FOR USE” section of the label to determine if preplant incorporation is recommended. Apply to the soil surface as a broadcast application. Precipitation or irrigation is required to bring incorporated herbicide treatments into contact with germinating weed seedlings.
The amount of precipitation or irrigation required depends on existing soil moisture, soil type and percent organic matter content, but 1/3 to 3/4 inch is normally adequate. If weeds emerge after treatment, rotary hoe or shallowly cultivate immediately to improve performance.
NOTE: Do not incorporate unless specifically recommended in the label for the crop and herbicide treatment selected. Incorporation of this product and its labeled tank-mixtures on coarse soil types may reduce length of weed control due to leaching with rainfall or irrigation.
Shallowly incorporate the treatment into the upper 1 to 2 inches of the soil. Equipment should be operated at manufacturer’s designed speed for incorporation to ensure adequate mixing and distribution of the herbicide treatment in the soil. Equipment design, including any drag attachments, must be adequate to avoid soil ridging which may result in streaked or reduced weed control. Set equipment to work the soil NO DEEPER THAN 4 INCHES. Soil conditions, including moisture content and crop residue levels, must be suitable to allow thorough and uniform mixing with the equipment used for 1-pass incorporation.
Preemergence Surface Application—This product and all labeled tank mixtures except this product plus Command or Eptam or Treflan may be applied to the soil surface after planting and prior to either crop or weed emergence. Apply within 5 days of last preplant tillage. If weeds emerge after treatment, or if treatment is applied more than 5 days after last preplant tillage, rotary hoe or shallowly cultivate immediately to improve performance. Precipitation or overhead sprinkler irrigation is required after application to move the herbicide treatment into the weed germination zone. The amount of precipitation or overhead sprinkler irrigation required depends on existing soil moisture, soil type and percent organic matter content, but 1/3 to 3/4 inch is normally adequate. Performance is improved when moisture is received within 7 days after application and prior to weed emergence. High-intensity or excessive rainfall or excessive irrigation after application may reduce control.
Cultivation Information—Delay cultivation after application for as long as possible unless weeds or grasses emerge. Shallowly cultivate or rotary hoe immediately if weeds or grasses emerge. If cultivation is necessary because of soil crusting or compaction, set equipment shallow and minimize lateral soil movement to avoid dilution or displacement of the herbicide treatment. If a band application is used and weeds have emerged in the treated band, set cultivator to throw soil into the row covering the band. On peanuts, do not throw soil into the row.
When applied as directed under conditions described, this product and tank-mixtures of this product will control or reduce competition from the weeds listed. Refer to the crop on which treatment is intended to determine the rates and tank-mixtures recommended.
Refer in the label for tank mix information.
GRAIN SORGHUM (MILO)—CONVENTIONAL TILLAGE
NOTE: Each crop section of the label provides application rates for this product and tank-mixtures including this product. Applications which are not consistent with recommendations in the label may result in unsatisfactory weed control, injury to crops, persons or animals, or other unintended consequences. Refer to specific product labels for crop rotation restrictions and cautionary statements of all products used in these tank- mixtures, including precautions on soil pH sensitive varieties, minimum re-cropping interval and rotational guidelines.
Use the higher rates in the application rate ranges in areas of heavy weed infestation or where otherwise specified. If emerged weeds exist at planting, the application of a contact herbicide or tillage is recommended when possible to eliminate existing weeds. Do not apply when conditions favor drift.
Detailed information regarding “APPLICATION SYSTEMS” and “APPLICATION TIMING AND METHODS” should be carefully reviewed in conjunction with the information in this section. If the specific information in this section differs from the “PRODUCT INFORMATION”, the specific information should control.
