This invention relates generally to formulation of the active ingredient [methyl(oxo){1-[6-trifluoromethyl)-3-pyridyl]ethyl}-λ6-sulfanylidene]cyanamide and similar compounds dispersed in water-immiscible solvents.
Sulfoximines with insecticidal activity have widespread utility for the control of insect. One particularly useful sulfoximine in this regard is a compound called sulfoxaflor, which is its common name, [methyl(oxo){1-[6-trifluoromethyl)-3-pyridyl]ethyl}-λ6-sulfanylidene]cyanamide, which is its IUPAC name, and N-[methyloxido[1-[6-(trifluoromethyl)-3-pyridinyl]ethyl]-λ4-sulfanylidene]cyanamide, which is its CAS Name. It has the following structure.
Despite the utility of sulfoximines, the ability of these compounds to efficiently control insect varies with a large number of parameters including, but not limited to, the species of insect to be controlled, the types of plant to be protected and the ambient conditions, such as temperature, humidity, hydration, length of day, biological diversity of the micro environment, and the like. Accordingly, there is a need for formulations of sulfoximines that extend the utility and/or increase the efficacy of these compounds. One object of the invention is to address this need.
Some aspects of the invention include sulfoximines with insecticidal activity, such as sulfoxaflor, formulated into oil dispersion using water-immiscible solvents for the control of insects. Insects that can be controlled using these formulations include, but are not limited to, sucking insects such as aphids. In some embodiments, the formulation may further include one or more of the following compounds: emulsifiers, coolants, dispersants, thickening agents, bactericides, bacteriostats, antioxidants, ultra violet light absorbing molecules, and other agriculturally active ingredients such as other insecticides, miticides, fungicides, herbicides, and the like.
Still other aspects of the invention include methods of controlling insect infestations by applying formulations that include sulfoximines, such as [methyl(oxo){1-[6-trifluoromethyl)-3-pyridyl]ethyl}-λ6-sulfanylidene]cyanamide, formulated into oil dispersion using water-immiscible solvents by applying these formulations to areas adjacent to or susceptible to insect infestation.
For the purposes of describing the principles of the novel technology, reference will now be made to the particular embodiments thereof, and specific language will be used to describe the same. It will, nevertheless, be understood that no limitation of the scope of the novel technology is thereby intended, such alterations, modifications, and further applications of the principles of the novel technology being contemplated as would normally occur to one skilled in the art to which the novel technology relates.
Pests, such as whiteflies of the genus Bemisia, are responsible for crop damage in many parts of world. Particularly damaging species include B. tabaci and B. argenifolii. Whiteflies infect a wide variety of very important crop plants, such as beans, tomatoes, cassava, cotton, potatoes, and sweet potatoes. Historically, these insects have been especially problematic in the tropical and subtropical regions. These insects feed by inserting their mouthparts into the phloem of the plant and sucking water and nutrients from the plant, thereby depriving the plant of nutrients and reducing its turgor. Additionally, the wounds that they create in the plants from which they feed provide an avenue for viral infection. In fact, many very harmful plant viruses may have evolved an ability to exist in whitefly secretions as their presence there provides them with ready access to plants that they are able to infect.
Whiteflies, like many insects that infest crop plants, have demonstrated a remarkable ability to evolve resistance to frequently used insecticides. Accordingly, the introduction of sulfoximines, such as sulfoxaflor, with insecticidal activity towards these types of insects is a welcome addition to the ranks of compounds that can be used to treat infestations of these and other susceptible insects. For additional information on these insecticides, see, for example, U.S. Pat. No. 7,687,634 issued on Mar. 30, 2010, which is incorporated herein by reference in its entirety.
In order to minimize the amount of insecticide that needs to be applied to a given area to control, rollback, contain, or prevent an infestation of damaging insects and thereby reduce the cost of using the insecticide, it may be useful to formulate the insecticide in a formulation that increases its ability to control the target insect. Additional design considerations that go into providing an insecticidal formulation with increased utility include its stability both in storage and after application, ease of dispersion, and rate of insect control.
Given the vast array of additives that can be combined with an insecticide to produce formulations of a new insecticide that has advantageous properties, the development of these formulations may require extensive, expensive and commercially risky investment in time and resources. Additionally, the complex interplay between agriculturally active ingredients, other components in a given formulation as well the interplay between the various plant species and the insects that attack those plants make success in this field unlikely. Aspects of the invention disclosed herein include formulation of compounds, such as Sulfoxaflor, and water-immiscible components to create an Oil Dispersion (OD) of Sulfoxaflor in a suitable carrier.
Sulfoximines for use with the present invention can be utilized in sufficient amounts to provide insecticidal activity. According to a particular embodiment of the invention, about 10% to about 50% by weight of the total insecticidal formulation of sulfoximine can be used at any specific amount within the stated range. In another embodiment of the invention, about 12% to about 48% by weight of sulfoximine can be used at any specific amount within the stated range. In yet another embodiment, about 20% to about 40% of sulfoximine can be used at any specific amount within the stated range.
Various non-water-miscible solvents that can be used in these formulations include, but are not limited to, one or more petroleum distillates, such as: aromatic hydrocarbons derived from benzene, such as toluene, xylenes, other alkylated benzenes and the like, and naphthalene derivatives, aliphatic hydrocarbons such as hexane, octane, cyclohexane, and the like, mineral oils from the aliphatic or isoparaffinic series, and mixtures of aromatic and aliphatic hydrocarbons; halogenated aromatic or aliphatic hydrocarbons; vegetable, seed or animal oils such as soybean oil, rape seed oil, olive oil, castor oil, sunflower seed oil, coconut oil, corn oil, cotton seed oil, linseed oil, palm oil, peanut oil, safflower oil, sesame oil, tung oil and the like, and C1-C6 mono-esters derived from vegetable, seed or animal oils; C1-C6 dialkyl amides of C6-C20 saturated and unsaturated aliphatic carboxylic acids, such as, N—N-dimethyl alkyl amide; C1-C12 esters of aromatic carboxylic acids and dicarboxylic acids and C1-C12 esters of aliphatic and cyclo-aliphatic carboxylic acids; C4-C12 polyesters of dihydric, trihydric, or other lower polyalcohols such as, propylene glycol dioleate, di-octyl succinate, di-butyl adipate, di-octyl phthalate and the like.

Other compounds and materials may be added provided they do not substantially interfere with the attractant activity of the composition of the invention. Whether or not an additive substantially interferes with the attractant activity can be determined by standard test formats including those that involve direct comparisons of the efficacy of the formulations of the present invention without at least one added compound and the composition of the present invention with at least one additional compound.
A pregel including about 1.5 wt % of Rilanit Plus® was made before assembling the formulation. The pregel was formed by adding Rilanit Plus® powder to a clean vessel with the designed amount of solvent (See Table 1), heating it to about 70° C., and holding it at that temperature for about 5 minutes. The formulation was completed by adding solvent (i.e., Exxsol D-130, Soybean oil and Aromatic 200ND), pregel, surfactants, and sulfoxaflor into a clean vessel under constant mixing. The mixture was then placed into a medium mill and ground for about 5 minutes using 1 mm glass beads. After milling, the formulation was packaged into a glass container for further evaluation.

The solvent methylated soybean oil was added into a clean vessel, next Aerosil R974 was added to vessel during a period of high shear mixing using a Silverson bench top batch homogenizer. After R974 was fully dispersed, the other ingredients (listed in Table 1) were added to the mixture in no particular order. The resulting mixture was homogenized for about five minutes to furnish the final formulation.
The standard formulation used as comparison in this invention was an aqueous suspension concentrate of sulfoxaflor with an active ingredient concentration of 240 g/L.
Cotton plants were infested with whitefly eggs and plants with uniform infestation were selected for trial. Experimental formulations were diluted to the appropriate concentration in water and spray application was made when eggs hatched to become crawlers using a track sprayer calibrated to deliver 200 L/ha. Whitefly control from each treatment was determined by counting number of 4th instar nymphs (red-eye) using a stereoscope. Experiments were carried out at two rates of a. i. (800 ppm and 200 ppm) for each formulation treatments with four replicate plants tested for each concentration.
Referring now to Table 3, results from testing these formulation on cotton plants (Table 3) demonstrate improved whitefly control from OD formulations D and A) at both concentrations (800 ppm and 200 ppm) over Std. formulation. Moderate level of control was obtained with Std. at 800 ppm (46%), but excellent control (92%) was obtained with formulation D and very good control was obtained with formulation A (78%).
The study was repeated. Referring now to Table 4 in the second study, as in the first study, better whitefly control was obtained by the addition of blank Oil Dispersed (OD), to Std. and from OD formulations (B, C, and A) than from treatment with only the Std. formulation. Whereas only 45% control was obtained with Std. at 800 ppm, enhanced whitefly control was obtained from addition of blank OD to 800 ppm Std. (66-89%) and from OD formulations at 800 ppm (70-72% control). Only marginal whitefly control was obtained from blank OD treatments. These results clearly indicate enhanced whitefly control from sulfoxaflor when formulated as an OD over an SC formulation.
Using standard foliar application equipment, various formulations of a sulfoxaflor insecticide were applied to plots of broccoli plants that were infested with Thrips tabaci (Thrips). At various intervals after treatment, five leaves were randomly collected from plants in each plot and placed into a solution of alcohol. The alcohol treated leaves were brought into the laboratory and the number of Thrips on each leaf was counted under a dissecting microscope. Each experiment was repeated four times.
The data collected in this study was transformed using Log(X+1) and analyzed using analysis of variance and the Student-Newman-Keuls test to compare the various treatments applied to the plants. Eight days after treatment, plants that were treated with the Standard formulation (Std.) did not have significant fewer Thrips than plants that were untreated, while plants treated with the formulations showed statistically significant fewer Thrips than the untreated plants.
Referring now to Table 5. Formulation D provided significantly better control of thrips 3 days after its application than did the Std. formulation. Formulation D also provided numerically better control 8 and 17 days after its application than did the Std. formulation.
