Embodiment 1
[0012] 1. Example 1: Preparation of 10% Benthiazone Mesotrione Suspending Concentrate
[0013] 1. Weighing:
[0014] Benthiazone 4%
[0015] Mesotrione 6%
[0016] Nonylphenol ethoxylate (NP-9) (dispersion wetting agent) 8%
[0017] Propylene glycol (antifreeze) 1%
[0018] Xanthan gum (thickener) 1%
[0019] Silicone defoamer (SAG612) 2%
[0020] Water (filler) 78%
[0021] 2. Weigh the materials according to the above weight ratio, stir and mix them evenly, and then sand them with a sand mill to obtain the product.
[0022] 3. Example of application:
[0023] By the product application rate of 30 milliliters / mu, 40 milliliters / mu, 50 milliliters / mu of the present invention.
[0024] The following table is a summary table of the density control effect test on the 20th day for the control of weeds such as crabgrass, barnyardgrass, and retroverted amaranthus in cornfields using 10% thiafentrazone-mesotrione SC:

[0031] 2. Example 2: Preparation of 20% Benthiazone Mesotrione WP
[0032] 1. Weighing:
[0033] Benthiazone 8%
[0034] Mesotrione 12%
[0035] NNO (dispersant) 3%
[0036] Sodium lignosulfonate (dispersant) 7%
[0037] Sodium alkylbenzene sulfonate (dispersant) 1%
[0038] Silica (filler) 69%
[0039] 2. After stirring and mixing evenly, the product is obtained by sanding with a sand mill.
[0040] 3. The control effect of the preparation on weeds such as corn crabgrass, barnyardgrass, and amaranthus at the application rate of 10 g / mu, 15 g / mu, and 20 g / mu is also above 90%, and it is also excellent. It is used alone for the two products of thiaflumezone and mesotrione.
[0041] The following table shows the control effect (%) of annual weeds in cornfields by using 20% thiafentrazone-mesotrione WP - the summary table of the plant control effect test 45 days after application:
