Embodiment 1

[0024] The emulsifiable concentrate is produced according to the above process according to the following weight percentages of each component: 5% of oxyfluorfen, 40% of sec-butaline, 10% of emulsifier OP-10, and 45% of solvent xylene. Indoor toxicity test results (Table 1, Table 2) show that the co-toxicity coefficients of the compound herbicide of this embodiment to grass weeds and broad-leaved weeds are 215.8 and 164.2 respectively, and the synergistic effect is remarkable. Field efficacy test result (table 3) shows, this embodiment compound herbicide is at 200,400,600,800g a.i. / hm 2 At the same dosage, the control effect of gramineous weeds is 85.5%-95.4%, the control effect of broad-leaved weeds is 89.8%-96.8%, and the effect of peanut production increase is 13.2%-33.3%, which are higher than oxyfluorfen , Zhongbuling used alone, which shows that compared with oxyfluorfen and Zhongbuling used alone, the compound herbicide of this embodiment can obviously expand the herbic...

Embodiment 2

[0026] The emulsifiable concentrate was produced according to the above process according to the following weight percentages of each component: oxyfluorfen 7%, sec-butaline 37%, emulsifier NP-10 12%, solvent xylene 44%. Indoor toxicity test results (Table 1, Table 2) show that the co-toxicity coefficients of the compound herbicide of this embodiment to grass weeds and broad-leaved weeds are 191.1 and 176.5 respectively, and the synergistic effect is remarkable. Field efficacy test result (table 4) shows, this embodiment compound herbicide is at 200,400,600,800g a.i. / hm 2 At the same dosage, the control effect of gramineous weeds is 86.3%-94.2%, the control effect of broad-leaved weeds is 89.6%-97.6%, and the effect of peanut production increase is 8.0%-30.6%, which are higher than oxyfluorfen , Zhongbuling used alone, which shows that compared with oxyfluorfen and Zhongbuling used alone, the compound herbicide of this embodiment can obviously expand the herbicidal spectrum, i...

Embodiment 3

[0028] The emulsifiable concentrate was produced according to the above process according to the following weight percentages of each component: 10% of oxyfluorfen, 35% of sec-butaline, 15% of emulsifier By-30, and 40% of solvent xylene. Indoor toxicity test results (Table 1, Table 2) show that the co-toxicity coefficients of the compound herbicide of this embodiment to grass weeds and broad-leaved weeds are 164.9 and 172.2 respectively, and the synergistic effect is remarkable. Field efficacy test result (table 5) shows, this embodiment compound herbicide is at 200,400,600,800g a.i. / hm 2 At the same dosage, the control effect of gramineous weeds is 88.8%-95.4%, the control effect of broad-leaved weeds is 88.0%-96.2%, and the effect of peanut production increase is 15.6%-33.8%, which are higher than oxyfluorfen , Zhongbuling used alone, which shows that compared with oxyfluorfen and Zhongbuling used alone, the compound herbicide of this embodiment can obviously expand the herb...

Abstract

The invention relates to a composite herbicide for peanut fields, which belongs to the field of pesticide and comprises the following components by weight: 1 percent to 30 percent of oxyfluorfen, 1 percent to 45 percent of butralin, 2 percent to 20 percent of emulsifier and 5 percent to 96 percent of solvent. The composite herbicide for peanut fields is sprayed in the weed preemergence soil of a peanut field to effectively remove grassy weeds and broad-leaved weeds and can widen a weed control spectrum, improve the weed control flexibility, increase the peanut yield and decrease the drug cost as compared with the single use of oxyfluorfen or butralin.

Description

technical field [0001] The invention relates to a compound herbicide for peanut fields, which belongs to the field of pesticides. Background technique [0002] Peanut is one of the three major oil crops in my country, and it is divided into spring peanut and summer peanut according to the planting time. As peanuts are low-growing crops, they are harmed by weeds during the entire growth period. In addition, spring peanuts are mostly planted with plastic film. The high surface temperature and high humidity are conducive to the growth of weeds, and the plastic-coated peanuts cannot be used for intertillage and weeding. , and the growing season of summer peanuts is hot and rainy, and weeds grow vigorously, so chemical control of weeds in peanut fields is particularly important. Most of the existing herbicides for peanut fields have problems such as narrow herbicidal spectrum and unsatisfactory weed control effect. It has good control effect on broad-leaved weeds and poor contr...
