Definitions

  • the present disclosure relates to a herbicidal combination for wide spectrum control of weeds. More specifically, the present disclosure relates to herbicidal combinations comprising pelargonic acid or salts or esters thereof, and at least one herbicide comprising Protoporphyrinogen oxidase (PPO) inhibitor(s) and Photosystem II (PS II) inhibitor(s). It also relates to a method of preparing a herbicidal combination, method of controlling weeds and methods of using such combinations.
  • PPO Protoporphyrinogen oxidase
  • PS II Photosystem II
  • An effective weed control can be achieved by appropriate use of herbicides.
  • the herbicidal activity can be enhanced in various ways to achieve maximum benefit.
  • One of the ways to enhance activity is to use combinations. However, identifying appropriate combinations, their agrochemical application rates, and ratio of the combination of agents is essential to achieve efficacious weed control. The selection of a particular formulation type is more cumbersome for an agrochemical combination. Thus, herbicides play an important role for weed control in crop production. Applying combinations of herbicidal compounds may enhance herbicidal effectiveness.
  • Pelargonic acid (( ⁇ (C ⁇ CC ⁇ H, n-pelargonic acid) is a saturated, nine- carbon fatty acid (C9:0), naturally occurring as esters in the essential oil of Pelargonium spp. It is applied as contact burndown herbicide, which attacks cell membranes and then as a result, cell leakage is caused and followed by membrane acyl lipids breakdown.
  • Pelargonic acid nonanoic acid a non- selective, broad-spectrum foliar herbicide that can be used to control plant growth during emergence. Pelargonic acid is active against a broad spectrum of annual and perennial weeds, mono and dicotyledons, algae and mosses.
  • Its herbicidal activity is typically in post-emergence weed control, that is contact activity at foliar level.
  • Pelargonic acid generally acts as a contact desiccant on aerial parts of weeds to which the product is applied. Phytotoxic effects due to application of pelargonic acid are visible in a very short time after spraying and symptoms involve phytotoxicity of plants and their cells, which rapidly begin to oxidize, and necrotic lesions are observed on aerial parts of plants.
  • WO 93/09669 describes aqueous formulations of organo-ammonium salts of herbicidal fatty acids such as, for example, the isopropyl ammonium salt, tryptamine salt, n-amylamine salt, n-hexylamine salt or sec-butylamine salt of pelargonic acid. These salts display herbicidal activity which is supposedly comparable to that of free pelargonic acid.
  • the odour of such formulations is a disadvantage, specifically in the case of alkylamine salts of low-molecular-weight alkylamines.
  • Alkylamine salts with a hydrophobic alkyl radical, i.e., an alkyl radical with a higher molecular weight are toxicologically problematic and are, as a rule, insufficiently biodegradable.
  • herbicidal combinations may not always result in the desired effect, they may result in an additive or an antagonistic effect. It may also result in phytotoxicity to crops, thus making it an undesirable combination. Consequently, herbicides need to be carefully selected so that they can be combined to offer a synergistic effect in weed control while having no phytotoxic effect on the crop and reducing the chances of weeds developing resistance to a particular herbicide.

  • Chemical mixtures can have an antagonistic effect when mixed, where the results are less than expected when the chemicals are combined.

  • a synergistic result is rare and typically only observed in results from high concentrations.

  • the expected (or predicted) response of a combination of herbicides is calculated by taking the product of the observed response for each individual component of the combination when applied alone divided by 100 and subtracting this value from the sum of the observed response for each component when applied alone.
  • An unexpected enhancement in efficacy of the combination is then determined by comparing the observed response of the combination to the expected (or predicted) response as calculated from the observed response of each individual component alone. If the observed response of the combination is greater than the expected (or predicted) response, or stated conversely, if the difference between the observed and expected response is greater than zero, then the combination is said to be synergistic or unexpectedly effective.
  • the percent control is greater than that predicted by the Colby formula or stated conversely, if the difference between the observed control and the expected control is greater than zero; then unexpected enhancement in activity is acknowledged.
  • the degree to which the difference is greater than zero is not itself critical as long as it is greater than zero; however greater the difference, more significant is the enhancement or the unexpectedness in weed control.
  • Example 1 Determining efficacy of weed control using a combination of Amicarbazone and pelargonic acid
  • Example 2 Determine average broad leaf weed efficacy using a combination of pelargonic acid with Amicarbazone
  • Table 2 shows average broad leaf weed efficacy using a combination of pelargonic acid with Amicarbazone:
  • Amicarbazone provides broad leaf efficacy in the range of 90-95%. Thus, it is evident that the combination of Pelargonic acid and Amicarbazone provides enhanced synergistic effect.
  • Table 3 shows efficacy against Amaranthus palmeri (AMAPA) using a combination of pelargonic acid and Amicarbazone:
  • Example 3 Determine potential of amicarbazone to improve grass control efficacy of pelargonic acid:
  • Example 5 Determination of the effect of combination of Sulfentrazone, Metribuzin and Pelargonic Acid in grass and broadleaf weed control:
  • a mixture of Sulfentrazone + Metribuzin was added to Pelargonic Acid to test the efficacy of said combination in grass and broadleaf weed control. Said mixture was added to 30%v/v of Pelargonic acid. The application amount of pelargonic acid was 30,200 g ai/ha.
  • Example 7 % grass control benefit from adding Nicosulfuron to mixes of Pelargonic Acid + Metribuzin and Sulfentrazone:
