After 20.6 parts of clothianidin, 0.08 parts of an isothiazolin-3-one derivative (BIOHOPE L, manufactured by K-I CHEMICAL INDUSTRY CO., LTD.), 0.3 parts of a silicone anti-foaming agent (ANTIFOAM E-20, manufactured by Kao
Corporation), 6.0 parts of propylene glycol, 2.0 parts of polyoxyalkylene aryl phenyl ether sulfate ammonium
(NEWKALGEN FS-7PG, manufactured by TAKEMOTO OIL & FAT Co., Ltd.), 3.0 parts of an aqueous solution of sodium
polyacrylate (43% by weight of sodium polyacrylate; TOXANON GR-31A, manufactured by Sanyo Chemical Industries, Ltd.), 0.6 parts of sodium montmorillonite (Kunipia F, manufactured by KUNIMINE INDUSTRIES CO., LTD.), and 1.0 part of an aqueous 35% sulfuric acid solution were added to 46.42 parts of ion-exchanged water and stirred, the mixture was wet- milled using DYNO-MILL KDL (manufactured by Shinmaru
Enterprises Corporation) , so that a milled suspension containing clothianidin (hereinafter referred to as milled suspension (d) ) was obtained.
On the other hand, 0.08 parts of xanthan gum (Rhodopol 23, manufactured by Rhodia Nicca) and 0.02 parts of an
isothiazolin-3-one derivative (BIOHOPE L, manufactured by Κ·Ι CHEMICAL INDUSTRY CO., LTD.) were dissolved in 19.9 parts of ion-exchanged water, so that an aqueous xanthan gum solution (hereinafter referred to as aqueous xanthan gum solution (D) ) was obtained.
Twenty parts of aqueous xanthan gum solution (D) was added to 80 parts of milled suspension (d) and stirred, so that a pesticidal aqueous suspension concentrate
(hereinafter referred to as comparative composition (2)) was obtained.
Next, Test Examples 1 to 4 were performed using the pesticidal aqueous suspension concentrates prepared as described above.
Test Example 1 (Measurement of Volume Median Diameter)
The volume median diameter was measured using a laser diffraction-type particle size distribution meter (HERO & RODOS, manufactured by Japan Laser Corp., measurement conditions: 20 mm in focal distance, a dispersion medium of ion-exchanged water) .
Test Example 2 (Measurement of pH)
The pH of the pesticidal aqueous suspension
concentrates was measured using a pH meter (Model F-22, manufactured by HORIBA Ltd. ) .
Test Example 3
The viscosity of the pesticidal aqueous suspension concentrates was measured at 25°C using a Brookfield
viscometer (Model RB-85L, manufactured by TOKI SANGYO CO.,
LTD., with rotor No. 2 at a number of revolutions of 6 rpm or 60 rpm) .
Test Example 4 (Measurement of Amount of Caking)
About 40 g of each pesticidal aqueous suspension concentrate was added to a 50 ml centrifuge tube and
subjected to centrifugation at a number of revolutions of 900 rpm for 6 hours. After the centrifugation, the
pesticidal aqueous suspension concentrate was discharged, while the centrifuge tube was vertically held with the opening facing downward. The discharging was stopped when the time interval between falling drops exceeded 10 seconds. The weight of the pesticidal aqueous suspension concentrate remaining in the centrifuge tube was measured at the time when the discharging was stopped, and the percentage
obtained by dividing the measured weight by the total weight of the pesticidal aqueous suspension concentrate used in the test was calculated as the caking rate. The result of each test example is shown in Table 1.
INDUSTRIAL APPLICABILITY
The pesticidal aqueous suspension concentrate of the invention resists caking and is useful as a pesticide formulation.
