Frequently Asked Questions about Product Use
In what types of rice or rice growing cultures will Rinskor™ active be used?
Concepts are being developed in seeded and transplanted rice in all major rice production areas globally. Rinskor can be used for weed control on Indica, Japonica and hybrid rice types and most important production systems, showing good selectivity over a wide window of rice stages. Other crop and non-crop uses for Rinskor are under evaluation.
Can Rinskor be tank mixed with other herbicides?
After registration, Rinskor can be applied in tank mix combinations with the most common pre-emergence and post-emergence herbicides in rice, to get residual weed control and to broaden the weed control spectrum. When tank mixing, follow label directions, including application rates as well as precautions and limitations of use on each herbicide label.
Would Rinskor control new weeds emerging after application?
No, Rinskor is a post-emergence herbicide that must come in contact with plant tissue to provide weed control. Rinskor will control exposed weeds at the moment of application.
What is the effective rate of Rinskor to control the proposed spectrum of weeds?
Rinskor will control a broad spectrum of weeds, including Echinochloa species at rates around 30 g ai/ha for foliar applications. The rate might vary according to factors such as weed development stage and weed spectrum, as well as local regulations.
Will I be able to mix Rinskor with other crop protection products (insecticides and fungicides) for effective crop management?
Yes, several tank-mix compatibility studies have been carried out by Dow AgroSciences to validate the possibility of mixing Rinskor with the most important crop protection products. In case of doubt refer to Rinskor literature or ask your Dow AgroSciences advisor.
You say Rinskor is a broad spectrum herbicide. Does this mean I will be able to manage my weed population with a single one-shot Rinskor application?
When registered products are available, Rinskor should be part of a weed management program that integrates effective cultural and herbicidal management practices. Although the Rinskor spectrum of control includes many important rice weeds, the use of other herbicides in mixture or in sequential applications may be needed to achieve effective control.
What is the maximum rate I will be able to use with Rinskor?
Maximum use rate is the one specified on the label. In most countries 30 g ai/ha for foliar applications is the label rate, and if allowed, it can be sprayed twice in the growing cycle for a maximum of 60 g ai/ha per growing cycle. The use of the product at higher rates is not supported/recommended by DAS as it would be a factor to increase risks for weed resistance to Rinskor. Higher rates could also increase the risk of crop injury.
Will I be able to add an adjuvant to the tank mix to improve Rinskor weed control?
Rinskor formulations have been properly balanced with the right amount of adjuvant to offer the required level of control while maintaining the best physical and chemical properties. The addition of extra adjuvant will not offer added benefits in terms of weed control.
If I have a crop of tomato/cotton/soybeans/sunflower adjacent to my rice crop that I am going to spray with Rinskor, should I be concerned about potential drift that will affect my adjacent crop?
Yes. Broad leaf crops are particularly susceptible to Rinskor. All Dow AgroSciences application recommendations should be followed to avoid or minimize drift risk that can affect susceptible neighboring crops. Refer to Rinskor literature for more information or ask your trusted Dow AgroSciences advisor.
Will I be able to spray Rinskor in late post-emergence as a rescue treatment? I have several weeds that escaped from an earlier herbicide application and heard the product will be very effective and selective at this timing.
Rinskor will not be recommended to be used as a salvation treatment when other herbicides have failed, and weeds are largely developed. Not only could you get partial control, but you would also be applying a herbicide to a crop that has already suffered from weed competition during the critical growing stages. The best practice is to apply Rinskor at the recommended timing and at the recommended weed size.
Will I be able to use Rinskor as part of my weed management program in my Clearfield rice system?
Yes, field work carried out by Dow AgroSciences has shown the compatibility and fit of the Rinskor program with the BASF Clearfield® production system* for rice. This will enable you to broaden weed spectrum, control ALS or ACCase resistant weeds and serve as an efficient resistance management alternative in these rice cropping systems.
Which formulations will be available with Rinskor?
Rinskor will be formulated as NeoEC™ SC, OD and GR formulations depending on market needs. All formulations have been designed to provide excellent tank mix dilution and compatibility. Additional formulations which contain Rinskor as well as other Dow AgroSciences herbicides such as penoxsulam and cyhalofop will also be available to support broader spectrum weed control and robust resistance management.
What are the spray methods recommended for Rinskor?
Rinskor can be applied by air or ground. To minimize spray drift, apply a total minimum spray volume of 100 liters / Ha using low pressure spray equipment designed to produce large droplets. Always read and follow the product label. In some regions of Asia a higher water volume may be used, based on local practice.
When is the best time to use Rinskor for weed control in rice?
Rinskor may be applied to rice from the 2 leaf stage with no exposed roots up to 60 days before harvest, or approximately at late boot stage. Weed stage is species-dependent. In general, grasses should be treated from 2 leaf to post-tillered stages, broadleaves up to 20 cm height and sedges up to 5 to 8 cm height.
Is Rinskor a broad-spectrum herbicide?
Rinskor has demonstrated control of all major types of weed in rice including grass, sedge and broadleaf weed species.
What are the weeds that Rinskor doesn't control well in the Rice crop?
Rinskor is a broad spectrum herbicide that provides control of most key grasses, broadleaves and sedges in rice. Please contact your local Dow AgroSciences representative for additional information on the spectrum of weeds controlled.
