The present invention relates to a combination of one or more herbicides and a safener for the selective control of weeds. More particularly, the present invention relates to a combination of one or more Triazolinone herbicides and one or more safeners for the selective control of weeds, with significant reduction in phytotoxicity.
Herbicides cause phytotoxicity when they are used in a higher dose than recommended, improper application methods, and wrong stage of crop growth. Certain herbicidal compounds can produce phytotoxic vapor during and after spray and thus contaminate sensitive crops and natural vegetation. Other instances of unwanted effects of herbicides on crops are lesser plant height or lesser number of plants standing after herbicidal treatments.
Therefore, the practice being used presently is the application of safeners along with herbicides to protect crop plants from herbicide injury.
Herbicide safeners are chemical agents that reduce the phytotoxicity of herbicides to crop plants without affecting the weed-control efficacy. However, it is pertinent to note that not all safeners have the desired beneficial effect of reduction in phytotoxicity with corresponding herbicides. Therefore, the challenges of identifying suitable herbicide-safener combinations that work efficiently to reduce phytotoxicity in crop plants and control weeds are persistent.
Flucarbazone-sodium is a Group 2 herbicide used for control of grassy and some broadleaf weeds in cereal crops. It belongs to the sulfonyl amino triazolinone class of herbicides. The field half-life of flucarbazone-sodium varies from 6 to 110 days in a range of prairie soils and is known to reduce plant weight. It is likely to persist in soil into the second growing season, particularly under conditions where decomposition is reduced and the phytotoxicity potential is considerably high because of its decreased adsorption in soil.
There is therefore a need in the art for safener combinations with Triazolinone herbicides, such as Flucarbazone that reduce their phytotoxicity, accompanied with a beneficial result in increased plant height and/or increased number of plants standing after herbicidal treatment.
The present invention, described hereinafter, achieves at least one of the following objects of the invention.

The invention will now be described in more details with reference to the following examples. While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above described embodiment, method, and following examples, but by all embodiments and methods within the scope and spirit of the invention.
Treatment: The present invention has employed a tank mix combination of Flucarbazone and Cyprosulfamid as the safener to evaluate its percentage phytotoxicity and its efficacy in the control of weeds. Additionally, to prove the synergy of the present herbicide combination of Flucarbazone and Cyprosulfamid, the present inventors have also used a Flucarbazone formulation individually in the form of wet dispersible granules to estimate its percentage phytotoxicity and the percentage efficacy control of weeds.
The tank mix combination of Flucarbazone and Cyprosulfamid as the safener was formulated and the combination was sprayed onto corn crop and the results on the phytotoxicity in corn were determined. These observations relating to % phytotoxicity were made during a time interval of over a month. The duration at which the % phytotoxicity were determined at time intervals as follows: 3 DAA (3 days after application), 5 DAA (5 days after application), 7 DAA (7 days after application), 14 DAA (14 days after application), 21 DAA (21 days after application); 28 DAA (28 days after application); 35 DAA (35 days after application); 42DAA (42 days after application).
Accordingly, the % phytotoxicity in corn crop was observed to be considerably reduced over a period of one month after application of herbicide combination, when the tank mix combination of Flucarbazone and Cyprosulfamid was employed. This % phytotoxicity was observed by the present inventors to be sustained at negligible levels up to 42DAA, with good crop yield and quality. On the other hand, the corn crop treated with Flucarbazone individually suffered significant damage over the time interval of one month, with % phytotoxicity levels reaching up to 50% at 14 DAA, with such % phytotoxicity levels being maintained even after 28DAA.
The tank mix combination of Flucarbazone and Cyprosulfamid as the safener was formulated and the combination was sprayed onto corn crop and the results on the efficacy in weed control were determined.
Accordingly, % efficacy in control of redroot pigweed in corn crop was observed to be considerably sustained over a period of one month, when the tank mix of Flucarbazone and Cyprosulfamid was employed. This % efficacy control of the redroot pigweed was observed by the present inventors to be sustained in the range of 60% to 70% over a duration of one month. On the other hand, the corn crop treated with Flucarbazone was observed to have a reduced % efficacy compared to the Flucarbazone and cyprosulfamid tank mix.
A) Flucarbazone with Isoxadifen as the Safener
B) Flucarbazone with Mefenpyr as the Safener
Accordingly, the % phytotoxicity in corn crop was observed to be significantly high over a period of one month, when the tank mix combination of Flucarbazone and Mefenpyr was employed.
This % phytotoxicity was observed by the present inventors to be as high as 56% at 14 DAA in crops treated with Flucarbazone and Mefenpyr. Further, phytotoxicity was observed even at 21 DAA and 28DAA. The highest phytotoxicity was observed at 35 DAA, with levels reaching as high as 60%. It is also vital to note here that phytotoxicity levels in corn crop, when Flucarbazone is used individually was almost at par and/or were reduced compared to the phytotoxicity levels of the combination of Flucarbazone and Mefenpyr.
Therefore, it was concluded that the phytotoxicity reduction in flucarbazone due to being combined with either cyprosulfamid or isoxadifen or both were surprisingly better and selective than that observed with mefenpyr.
The combination of flucarbazone with safeners selected from cyprosulfamid and isoxadifen were evaluated in terms of the increase or decrease in height of the treated corn crop (cm) and % phytotoxicity. The experimental evaluations were conducted under greenhouse conditions with 4 repetitions, using a spray volume of 150 L/ha. The different corn varieties tested were SYN8A98 TLTG and XB 8010.
The observations for determining corn height were made at 14 DAA (days after application) of the herbicide. The treatment employed and the corresponding observations are detailed in the table 8 (i) & (ii) below:
The height of the corn plants treated with the herbicide combination of flucarbazone and cyprosulfamid showed an excellent increase in height which was similar to the untreated corn crop. However, corn plants treated with flucarbazone individually showed reduction in height, further corn plants treated with the herbicide combination of flucarbazone and isoxadifen as the safener showed a further reduction in height.
The observations for determining corn height were made at 7 DAA (days after application), 14 DAA and 21 DAA, of the herbicide. The treatment employed and the corresponding observations are detailed in the table 9 (i) & (ii) below:
4 def
The % phytotoxicity on corn plants treated with the herbicide combination of flucarbazone and cyprosulfamid showed considerable reduction compared to flucarbazone applied individually and in the treatment including flucarbazone and isoxadifen. Therefore, the present inventors have successfully showed that the combination of flucarbazone and cyprosulfamid effectively reduced phytotoxicity in corn crop over herbicide combinations consisting of other safeners.
