The method is particularly suitable for controlling weeds in flooded rice fields. [Background technology]

[0002] Rice is the most important human food crop in the world, directly feeding more people than any other crop. Two rice species are important cereals for human nutrition: Asian rice (Oryza sativa L.) and African rice (O. glaberrima Steud.). Asian rice (O. sativa L.) constitutes almost all of the cultivated rice in the world and is also grown in the United States, especially in the Central Valley of California.

[0003] Weeds are a significant challenge in rice production and can be responsible for 59% yield loss due to watergrass (Echinochloa spp.) and up to 100% yield loss in dry-seeded systems in California (Brim-DeForest, WB, Al-Khatib, A. and Fischer, AJ (2017). Predicting yield losses in rice mixed-weed species infestations in California. Weed Science, 65, pp. 61-71). Major competing species include Echinochloa crus-galli, early-growing Echinochloa oryzoides, late-growing Echinochloa phyllopogon, and Leptochloa fusca.

[0004] Rice is a semi-aquatic crop that benefits from flooded soil conditions for part or all of the growing season. Rice production in the United States can be broadly classified as either dry-seeded or water-seeded. In a water-seeded system, rice is sown into a prepared seedbed either by drilling or by broadcasting the seed and incorporating it with a disk or harrow. Moisture for seed germination comes from irrigation or rainfall. An alternative method of planting with a water-seeded system is to broadcast the seed by airplane into a flooded rice field and then immediately drain the field. In a water-seeded system, once the seedlings reach a sufficient size (4- to 5-leaf stage), the field is permanently flooded with shallow water to a depth of 5-16 cm for the remainder of the harvest season. Rice varieties that grow quickly as seedlings are preferred to allow for the rapid application of permanent flooding to compete with weeds and suppress grassy weed growth. Residual-acting grass herbicides are also used to prevent new weed emergence.

[0005] In the flooded direct seeding system, the seed is soaked for 12-36 hours to initiate germination and then the seed is broadcast by airplane into flooded fields. This is the predominant rice production system in California. Some herbicides are applied pre-emergence (applied to the soil before flooding) and some are applied early on the day of sowing or during the first few weeks of rice seedling growth. Weed control at emergence or when the weeds are young helps to suppress weeds by reducing competition with the rice seedlings and speeding up rice growth and canopy closure. Weeds are also much easier to control early in their growth. Pre-emergence applications have an advantage to the grower in that they can be accomplished on the ground during the final stages of seedbed preparation as opposed to aerial applications when the field is flooded.

[0006] Aerial applications of pesticides are subject to regulations and restrictions due to potential drift or migration, and some rice herbicide materials cannot be applied by airplane in California. In some cases, the herbicide is a granule that disperses in the rice field to control the weeds, rather than a liquid spray. This is highly advantageous to prevent drift or migration of the herbicide from the target field. Maintenance of permanent flooding aids in the control of grass weeds, especially in combination with selective grass weed killers. However, aquatic weeds (e.g., sedges and rushes) are favored by permanent flooding. Flooded direct seeding systems are conducive to water infrastructure, field delivery, and management in California. Rice seedlings emerge from shallow flooding, or the field may be drained for short periods to improve seedling establishment. Lowering the water level improves seedling establishment by providing additional oxygen to promote root growth and better establishment of seedlings against eradication by wind and wave action. It also exposes weeds to contact herbicide applications. However, it encourages grass weed growth, nitrogen loss, and increased water consumption and management. Herbicide use on rice can damage the rice, reduce growth, shorten stature, and delay maturity, potentially reducing yield. Field drainage or lowering the water level is used to reduce chemical injury. However, this may not be possible due to the water hold period required for the herbicide and water management and use efficiency. In recent years, weed control in commercial rice production in California has become a major production problem for growers due to environmental regulations, the emergence of herbicide-resistant weeds, and the phasing out of older herbicides.

[0008] For example, saflufenacil is sold by BASF Corporation, Research Triangle Park, NC, USA under the trade name Kixor® for use in certain crops, including, inter alia, rice. Saflufenacil is the common name of a herbicidal compound with the IUPAC name N'-{2-chloro-4-fluoro-5-[1,2,3,6-tetrahydro-3-methyl-2,6-dioxo-4-(trifluoromethyl)pyrimidin-1-yl]benzoyl}-N-isopropyl-N-methylsulfamide and the Chemical Abstracts name 2-chloro-5-[3,6-dihydro-3-methyl-2,6-dioxo-4-(trifluoromethyl)-1(2H)-pyrimidinyl]-4-fluoro-N-[[methyl(1-methylethyl)amino]sulfonyl]benzamide (described in The e-Pesticide Manual, Version 5.2, British Crop Production Council, 2008-2011, entry 770). The herbicidal activity of saflufenacil is described in WO 01 / 083459. A crystalline, essentially solvent-free form of saflufenacil is described in WO 08 / 043835. Two crystalline hydrate forms of saflufenacil are described in WO 08 / 043836.

[0009] ER Camargo et al., “Rice Tolerance to Saflufenacil in Clomazone Weed Control Program”, International Journal of Agronomy, 2011(4), DOI:10.1155 / 2011 / 402461, describes the evaluation of rice tolerance to saflufenacil in a clomazone weed control program. Saflufenacil was applied pre- and post-emergence and before flooding of drill-sown rice.

[0010] Nevertheless, there remains a need to control weeds, particularly aquatic weeds, in rice. Similarly, it is desirable to develop practices to prevent, slow, or manage herbicide-resistant weeds, particularly aquatic weeds, in rice. Furthermore, there remains a need to control weeds, particularly aquatic weeds, in rice while preventing or minimizing damage and / or yield loss to the crop species.

[0362] The following examples serve to illustrate the invention. EXAMPLES

[0363] 1. General Procedure A formulation of specific herbicide A was examined at various rates and timing for weed control, phytotoxicity, and rice yield in a flooded direct seeded rice system. The following experiment is conducted in a silty clay soil at the Rice Experiment Station (Biggs, California, USA). The experiment is conducted as a completely randomized block design with three replicates. Plot size is 10 feet (3.048 m) by 20 feet (6.096 m) with individual ridges around each plot to prevent contamination of the herbicide from plot to plot.

[0364] Suitable herbicide A formulations may include, for example, an emulsifiable concentrate (EC), a capsule suspension (CS), a granule (GR), or a suspension concentrate (SC). Each herbicide A formulation may be applied, for example, 5, 10, or 15 days after seeding (DAS) at a particular rate (kg ai / ha).

[0365] M-206 rice is sown by plane in May at a rate of 120 lb / A (134.5 kg / ha) and harvested as grain in October of the same year. This rate is used below the usual rate in grower fields (170-200 lb / A, which is equivalent to 190.54-224.17 kg / ha) to allow for greater weed penetration in the field. Fields are flooded the day before sowing and maintained at a depth of 4 inches (10.16 cm) throughout the growing season. Water is discontinued one month prior to harvest.

[0366] The CS, EC, and / or SC formulations of Herbicide A are applied at 20 gal / A (187.08 l / ha) using a 10 ft (3.048 m) two-person boom sprayer, sprayed underwater at 30 psi (2.07 bar) with a CO2 backpack and 3 miles per hour (4.83 km / h) with a Flat Fan 8003 nozzle. The GR formulation of Herbicide A is applied by hand to each corresponding plot.

[0367] Visual percentage assessment of rice injury is collected as chlorosis, dwarfing, bleaching, and stand reduction at 40 days after treatment (DAT). 2The total number of rice seedlings and tillers per stalk was collected at 75 DAS. Plant height was recorded at 108 DAS. Visual percentage assessments of weed control were recorded for each weed present at 14, 24, or 56 DAT, and included in particular Echinochloa spp., e.g., Echinochloa crus-galli (ECHCG, common barnyard grass) and Echinochloa oryzicola (ECHCR, late watergrass), and Leptochloa fusca, e.g., Leptochloa fusca subsp. fascicularis (LEFFA, bearded sprangletop), as the most significant weeds, but also sedges and broadleaf weeds, e.g., Cyperus persicae (Cyperus spp.), as well as sedges and broadleaf weeds, e.g., Cyperus serrata (Cyperus serrata ... The treatments include those for Cyperus difformis (CYPDI, small-flower umbrella sedge), Ammannia auriculata (AMMAU, redstem), Bacopa monnieri (BAOMO, Monnier water hyssop), Heteranthera limosa (HETLI, duck salad), and Schoenoplectiella mucronata (SCPMU, rice-field bulrush). Untreated plots are used as the base or zero for visual percentage assessments for both rice injury and weed control. Rice yield is determined at 14% moisture. 21 sq. ft. 2) area of ​​rice is cut from the center of each plot and a thresher is used to separate the seeds from the stalks. The seeds are washed to obtain moisture and then weighed to determine yield. Data are analyzed by analysis of variance (ANOVA) and least significant difference (LSD) test (significance level p=0.05) using ARM software (GDM Solutions, Inc. 2020).

[0368] 2. Field test using saflufenacil as herbicide A The saflufenacil formulations detailed below were examined for weed control and phytotoxicity in a flooded direct seeded rice system. The following experiment was conducted on a silty clay soil at the Rice Experiment Station (Biggs, California, USA). The experiment was conducted as a completely randomized block design with three replicates. Plot size was 10 ft (3.048 m) x 20 ft (6.096 m) with individual ridges around each plot to prevent contamination of the herbicide from plot to plot.

[0369] Saflufenacil was applied in two formulations: Sharpen®, a suspension concentrate (SC) formulation available from BASF Corporation and containing 29.74% saflufenacil, and a CS formulation having an active ingredient concentration of 130 g / L.

[0370] Each formulation of saflufenacil was applied at rates of 0.05 and 0.1 kg / ha at 10 days after sowing (DAS).

[0371] M-206 rice was sown by plane in May at a rate of 120 lb / A (134.5 kg / ha) and harvested as grain in October 2021. This rate, which is lower than grower field rates (170-200 lb / A equivalent to 190.54-224.17 kg / ha), was used to allow for more weed infestation in the field. Fields were flooded the day before sowing and maintained at a 4 inch (10.16 cm) water depth throughout the growing season. Water was discontinued one month prior to harvest.

[0372] The CS and SC formulations of saflufenacil were applied at 20 gal / A (187.08 l / ha) using a 10 ft (3.048 m) two-person boom sprayer, sprayed underwater at 30 psi (2.07 bar) with a CO2 backpack and 3 miles per hour (4.83 km / h) with a Flat Fan 8003 nozzle.

[0373] A visual percentage assessment of rice injury was collected as stand reduction at 40 days after treatment (DAT). 2 The total number of rice seedlings and tillers per stalk was collected at 75 DAS. Plant height is recorded at 108 DAS. Visual percentage assessments of weed control were recorded for individual weeds at 56 DAT (see Table 1 below).
