Embodiment 1
[0013] In this implementation, the active ingredient mass content is firstly prepared to be 30% fenflumezone · fenflumezone suspending agent, and the specific mass components are:
[0014] Mefentrazone 10%
[0015] Benthiazone 20%
[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) 58%
[0021] Weigh the materials according to the above mass ratio, stir and mix them evenly respectively, and obtain the suspending agent made by the product according to the above ratio through sand mill sand grinding, and use 30 ml / mu, 40 ml / mu, 50 ml / mu for corn field horses Tang, barnyardgrass, retroverted amaranthus, foxtail, goosegrass, purslane, amaranthus and other weeds have a control effect of more than 90%. , the effective ingredient is 40% thiafentrazone oil emulsifiable concentrate to carry out the same piece of corn field w...
Embodiment 2
[0029] In this implementation, we first prepare a wettable powder with an active ingredient mass content of 20% fenflumezone · fenflumezone, and the specific mass components are:
[0030] Mefentrazone 5%
[0031] Benthiazone 15%
[0032] NNO (dispersant) 3%
[0033] Sodium lignosulfonate (dispersant) 7%
[0034] Sodium alkylbenzene sulfonate (humectant) 1%
[0035] Silica (filler) 69%
[0036] The preparation made according to the above ratio is applied to Chinese crabgrass, barnyardgrass, amaranth, foxtail, goosegrass, purslane, iron The control effect of amaranth and other weeds is also above 90%. At the same time, the active ingredient is 15% fenflumezone suspension concentrate at 50 ml / mu, and the active ingredient is 40% fenflumezone oil emulsifiable concentrate at 45 ml / mu. The same piece of cornfield weeding comparative example is implemented, and the weeding effect is shown in Table 4 and Table 5. As can be seen from the herbicide implementation effects in the ta...
