Embodiment 1

[0104] Example 1: Evaluation of herbicides and safeners for post-emergence foliar application in direct-seeding rice

[0105] Seeds and kernels of the plant species to be tested are planted in 80 to 20% mixed loam or sandy loam (e.g. 28.6% gravel, 18.8% clay and 52.6% sand at about pH 5.8 and about 1.8 % of organic matter content) and the soil matrix made of calcareous coarse sandy soil. The soil matrix was placed in 84.6 square centimeters (cm 2 ) surface area in a plastic basin. Fungicide treatments and / or other chemical or physical treatments are applied when necessary to ensure good germination and healthy plants. Plants were grown in a greenhouse for 8-22 days with an approximately 14 hour photoperiod maintained at approximately 29°C during the day and 26°C at night. Nutrient solution (Peters Excel 15-5-15 5-Ca 2-Mg and iron chelate) was applied to the irrigation solution and watered regularly as needed. A 1000W pendant metal halide lamp is provided as a supplementary...

Embodiment II

[0151] Example II: Evaluation of Herbicides and Safeners in Water for Transplanted Rice

[0152] The weed seeds or the nutrient solution of the plant species to be tested are dispersed in a 1:1 volume ratio by mixing non-sterile mineral soil debris (for example, 50.5% gravel, 25.5% clay and 24% sand at about pH 7.6 and About 2.9% organic matter content) and water made of silt soil (mud). Put the prepared mud into 86.59 square centimeters (cm 2 ) surface area in 16 ounce (oz.) non-porous plastic pots with 3 centimeters (cm) headspace in each pot. Sun Gro, which typically has a pH of 6.0 to 6.8 and an organic Rice seeds in the 306 planting mix were planted in plastic plug trays. Seedlings grown to the second or third true leaf stage were transplanted four days before herbicide application to a 32-oz. 2 ) surface area in a non-porous plastic basin. Fill the pot head space with 2.5 to 3 cm of water to form a paddy field. Fungicide treatments and / or other chemical or physica...

Abstract

A safened herbicidal composition for use in rice comprising a herbicidally effective amount of (a) a compound of formula (I): or an agriculturally acceptable salt or ester thereof and (b) a safener or a compatible herbicide capable of safening such as a chemical from the quinolinyloxyacetate family of chemicals, bicyclonon, daimuron, dimepiperate, fenclorim, furilazole, halosulfuron, isoxadifen-ethyl, mefenpyr-diethyl, naphthalic anhydride (NA), or agriculturally acceptable salts, esters, or mixtures thereof, for use in direct-seeded, water-seeded or transplanted rice.

Description

Background technique [0001] The protection of crops from weeds and other vegetation that inhibits crop growth is a recurring problem in agriculture. To help address this problem, researchers in the field of synthetic chemistry have produced a variety of chemicals and chemical agents that are effective in controlling the unwanted growth. Many types of chemical herbicides have been disclosed in the literature, and many are in commercial use. However, in addition to the weeds and other vegetation intended to be controlled, sometimes these herbicides can damage the crops being protected. Summary of the invention [0002] Provided herein are safe herbicidal compositions for use in rice comprising a herbicidally effective amount of a compound of formula I (a) [0003] [0004] or an agronomically acceptable salt or ester thereof, and (b) a safener or a compatible herbicide capable of acting safe, such as a chemical from the quinolyloxyacetate family of compounds (including bu...
