Embodiment 1

[0196] Example 1 -Liquid phase studies

[0197] The purpose of this study was to determine that the viscosity of the medium is lower when no active ingredient is present. The following solutions were prepared by adding the components and mixing with a Ross mixer. 10 mL of the sample was added to a 50 mL graduated cylinder, and the cylinder was shaken vigorously 20 times. The amount of foam is measured as a percentage of the volume of 50 mL. All readings were made with a Brookfield viscometer, LVTD, #3 spindle and setting F=2, measuring the viscosity of each sample at 30 rpm. Use pure samples for specific gravity measurements. A pH measurement of a pure sample was performed. Freezing and melting temperatures were determined by placing the sample in a -20°C freezer overnight and then heating the sample. Record the freezing temperature when the sample becomes completely fluid with no apparent ice crystals present. Tables 2 and 3 show the results of the liquid phase studie...

Embodiment 2

[0202] Example 2 - Aqueous suspension phase studies

[0203] The procedure of Example 1 was followed for the compositions of Tables 4 and 5. The mixture was prepared by first mixing the components and then grinding the contents with a Silverson mixer. Lignosulfonate media were studied to show that the viscosity of the media is generally lower when Al is not included. It was observed that some formulation media produced substantial foam when a non-ionic surfactant such as Agnique PG 9116 was present in the media. Freezing and melting points are not measured. Borresperse NA is sodium lignosulfate supplied by Lignotech (CAS No. 8061-51-6). Hi-Sil 233 is an aqueous amorphous silica gel available from PPG Industries, Inc with CAS No. 112926-00-8. Attagel 50 is an attagel clay available from Engelhard Corporation.

Embodiment 3

[0209] Samples 39 to 42 were prepared from a wet milled masterbatch of 328 g imidacloprid, 32 g Borresperse NA and 540 g water. Grinding was performed in a laboratory Dynomil grinding unit. After reaching a particle size of 2.6 μm (<50% mean volume), the resulting millbase was collected and subdivided. Salt and / or glycerin was added to each sample to complete the formulation (samples 39 to 42). The formulations showed surprising compatibility with the fertilizers tested (Table 6, 10-34-0, 3-18-18, and 6-24-6). A reference formulation (Sample 43, Table 6) was prepared using conventional compounds alone for comparison. Fertilizer compatibility tests in the present invention were performed to simulate field test conditions (0.22 lb active ingredient / 5 gallons of fertilizer); the corresponding laboratory ratio was 0.375 g active ingredient / 100 g fertilizer. The entire mixture was then filtered through a US Mesh 50 mesh and the net retained residue was measured and reported. Th...

Abstract

This invention relates to compositions compatible with liquid fertilizers and methods of use thereof.

Description

Technical field [0001] The present invention relates to compositions for agricultural and non-agricultural pest control applications, such as insect, weed and fungal control. Background technique [0002] In the field, many pesticide formulations are tank-mixed in liquid form with many other pesticides, adjuvants, etc. to maximize application efficiency. Many tank mix formulations contain two or more pesticides and / or fertilizers. [0003] Compatibility of fertilizers and pesticides in tank mix formulations has proven to be a persistent and thorny issue. For example, the chloronicontinyl (CNI) class of insecticides are known to be effective in agricultural and non-agricultural pest control. A common known problem with this class of insecticides and other pesticides is that of Compatibility of fertilizers, particularly liquid fertilizer compositions. Despite years of research, there is still no general solution to the incompatibility problem; although earlier practitioners...
