Description

Title: SUSPENSION CONCENTRATE COMPOSITIONS OF SPINOSYNSTECHNICAL FIELD OF THE INVENTIONThe present invention relates to novel suspension concentrate (SC) compositions comprising a spinosyn insecticide, at least one dispersing agent and particular additive. The SC compositions of the invention are stable and useful in controlling animal pests.BACKGROUND OF THE INVENTIONThe advent of the 'Green' Revolution in the mid-20th century marked a significant turning point in agricultural practices, as it brought about a substantial increase in crop yields worldwide. This revolution was primarily driven by the introduction of high-yielding crop varieties, improved irrigation techniques, and the extensive use of synthetic chemicals for pest control. Pesticides, such as insecticides, herbicides, and fungicides, played a crucial role in protecting crops from pests and diseases, thereby ensuring higher productivity and food security. The widespread adoption of these chemicals led to substantial gains in agricultural productivity, but concerns regarding their environmental impact and potential health risks necessitated a shift towards more sustainable alternatives.In recent decades, the agricultural industry has witnessed a transition towards the use of natural products as pesticides. This shift has been prompted by the implementation of stringent pesticide registration procedures, including the Food Quality Protection Act (FQPA) in the United States. The FQPA, enacted in 1996, mandated a comprehensive reassessment of pesticide safety and introduced a more stringent risk-based approach to pesticide regulation. Under the FQPA, greater emphasis was placed on evaluating the potential adverse effects of pesticides on human health (Dayan FE, Cantrell CL, Duke SO. Natural products in crop protection. Bioorg Med Chem. 2009 Jun 15;17(12):4022-34). This regulatory shift, combined with growing environmental concerns, has propelled the development and commercialization of natural product-based pesticides that offer effective pest control while minimizing ecological and health risks.Among the notable advancements in natural product-based pesticides, spinosyn insecticides have gained considerable attention due to their unique properties and commercial value. Spinosyns are naturally derived compounds produced from fermentation of the bacteriumSaccharopolyspora spinosa, and their unique mechanism of action involves disruption of nicotinic acetylcholine receptors. When compared with many other insecticides, the spinosyns generally show greater selectivity toward target insects and minor activity against many beneficial predators as well as mammals and other aquatic and avian animals.The commercial success of spinosyn insecticides can be attributed to their superior efficacy, broad spectrum of activity, and favorable safety profile. They have found extensive use in various agricultural settings, including field crops, vegetables, fruits, and ornamentals.Spinosad is a combination of the two principal fermentation factors, spinosyns A and D. Structure-activity relationships have been extensively studied, leading to development of a semisynthetic second-generation derivative, spinetoram.The development of spinosyn-based formulations promotes safer and more environmentally friendly pest control solutions offering effective pest management strategies while minimizing the potential risks associated with conventional chemical pesticides and will help farmers address pest resistance issues that arise from prolonged use of traditional synthetic chemicals.Suspension concentrate (SC) are formulations of a solid active ingredient(s) dispersed in water. To formulate a stable SC composition the active ingredient must remain insoluble under all temperature conditions. If an SC is not properly stabilized, the formulation can breakdown resulting in the solid particles either floating to the surface or settling down to the bottom of the commercial container depending on the relative density. This results in non- uniform distribution which leads to reduced shelf life and poor performance of the product in the field. To overcome this issue, when formulating SC, rheology modifiers are added by formulators as must-have components to provide compositions with increased viscosity therefore preventing sedimentation of the solid active ingredient. Examples of commonly used rheology modifiers are Xanthan gum (polysaccharide), Veegum® (magnesium aluminum silicate) hydrophilic silica, smectite, bentonite clay, cellulose and cellulose derivatives such as carboxymethyl cellulose.SUMMARY OF THE INVENTIONIt has now been found, in accordance with the present invention, that insecticidal suspension concentrate (SC) compositions comprising a spinosyn insecticide, at least one dispersingagent and particular additive, more specifically, poly alkoxylated alkyl ethers wherein the alkyl group contains from about 1 carbon atom to about 10 carbon atoms can be formulated without the incorporation of rheology modifier and still provide a stable uniformly dispersed SC composition.For example, and as shown in the Experimental section herein, particular such SC compositions comprising the spinosyn insecticide spinosad, a dispersant selected from Tersperse 2020 (Indorama) and Atlox 4913 (Croda) and the poly alkoxylated alkyl ether Atlas G5002 LQ (Croda) upon dilution with water, dispersed evenly and uniformly.This finding is highly important as it enables applying SC formulations comprising a spinosyn insecticide efficiently, without dealing with problems related to viscosity and pourability upon application, while maintaining the chemical stability of the solid active ingredient comprised within the SC formulations.In one aspect, the present invention thus relates to an insecticidal suspension concentrate composition comprising a) a spinosyn insecticide; b) at least one dispersing agent and c) poly alkoxylated alkyl ether wherein the alkyl group contains from about 1 carbon atom to about 10 carbon atoms.In another aspect, the present invention relates to methods for using an SC insecticidal composition as defined above.

Evaluation of the properties of the spinosad suspension concentrate formulations A-G

[0066] After the preparation of spinosad based formulations with various dispersing and wetting agents as described in Examples 1-7, 30 g of each formulation was subjected to storage stability test (at 54 °C for 2 weeks). Physical parameters such as dispersibility, viscosity and pourability were evaluated. The results and the various wetting agents tested are shown in Table 8.Table 8*The viscosity test was done using Brookfield AMETEK viscometer with spindle 62; speed 12 RPM.** The viscosity test was done using Brookfield AMETEK viscometer with spindle 63; speed 12 RPM.bThe suspensibility test was done in the presence of hard water which contain relatively high amount of ions. These ions may react with the active ingredient and with some of the formulation additives such as surfactants, adjuvants, and rheology modifiers, eventually causing distribution problems in water. However, in the case of formulations A-B excellent suspensibility was achieved.Suspensibility Test:This method is intended to determine the suspensibility which is defined as the percentage of one or more active ingredient(s) remaining in suspension after a given time. The method is applicable to formulations forming suspensions on dilution with water at sample concentrations between 0.1 % and 10 %.Outline of the method:A suspension of the formulation in Standard Water is allowed to remain undisturbed for a specified time at ambient temperature before the top 9 / 10ths are drawn off and the remaining l / 10th is assayed. The suspensibility is calculated as the percentage of particles remaining suspended.Procedure:1. 200 ml of water were inserted to 250 ml cylinder.2. 3.75 g of the formulation was inserted to the cylinder was dispersed in the water.3. Additional amount of water was added to complete the volume to 250 ml.4. The cylinder was Inverted 30 times for the granules to be fully dispersed.5. 225 ml of the suspension was drained using a vacuum pump.6. The rest of the suspension (25 ml) was left in the cylinder checked analytically using HPLC.Based on the analytical result for the amount of Al in the 25ml suspension, the calculation of the Suspensibility index was done using the formula in the CIPAC method MT184 (the acceptance Criteria for this specification is between 60% to 105%). [this procedure was taken from a different application, please advise if relevant]After storage stability tests formulations A and B (according to the invention) showed no sedimentation (no changes of physical properties) while maintaining relatively low viscosity therefore optimizing the fluidity and display a readily pourable / pumpable concentrate. Formulations C-G (not according to the invention) were highly viscous and had pourability problems.Example 9 - Preparation of a diluted spinosad suspension concentrate formulation HTo 80 gr taken from spinosad formulation A (see table 1) 7000 gr of water were added thus obtaining spinosad in an amount of about 0.5% by weight.Example 10 - Preparation of a diluted spinosad suspension concentrate formulation ITo 10 gr taken from spinosad formulation H 240 gr of water were added thus obtaining spinosad in an amount of about 0.02% by weight.Example 11 - Evaluation of efficacy of spinosad formulation for control of Thrips Tabaci in broccoliTable 9.
