Embodiment 1

[0009] test group:

[0010] Prescription: 20wt% fluroxypyr 20g, 56wt% sodium dimethyltetrachloride powder 15g, mixed with water 20kg.

[0011] Control group:

[0012] (1) Formula: 20wt% fluroxyl 35g mixed with water 20kg;

[0013] (2) formula: 56wt% sodium dimethyltetrachloride powder 35g mixed with water 20kg;

[0014] The above-mentioned experimental group, control group (1) and (2) are all applied to the Manila turf in the marked area by spraying, with an area of ​​1000m 2 , once every 4 days, and repeated 7 times in total, and counted the spraying effect on weeds.

[0015] The statistical results are as follows:

[0016] group Strain control effect (%) test group 94 Control group 1 85 Control group 2 78

[0018] test group:

[0019] Prescription: 20wt% fluroxypyr 20g, 56wt% sodium dimethyltetrachloride powder 10g, mixed with water 20kg.

[0020] Control group:

[0021] (3) Formula: 30 g of 20 wt% fluroxyl acetic acid mixed with 20 kg of water;

[0022] (4) formula: 56wt% sodium dimethyltetrachloride powder 30g mixed with water 20kg;

[0023] The above-mentioned experimental group, control group (1) and (2) are all applied to the Manila turf in the marked area by spraying, with an area of ​​1000m 2 , once every 4 days, and repeated 7 times in total, and counted the spraying effect on weeds.

[0024] The statistical results are as follows:

[0025] group Strain control effect (%) test group 92 Control group 1 83 Control group 2 76

Embodiment 3

[0027] test group:

[0028] Prescription: 20wt% fluroxypyr 20g, 56wt% sodium dimethyltetrachloride powder 13g, mixed with water 20kg.

[0029] Control group:

[0030] (5) Formula: 20wt% fluroxypyr 33g mixed with water 20kg;

[0031] (6) formula: 56wt% sodium dimethyltetrachloride powder 33g mixed with water 20kg;

[0032] The above-mentioned experimental group, control group (1) and (2) are all applied to the Manila turf in the marked area by spraying, with an area of ​​1000m 2 , once every 4 days, and repeated 7 times in total, and counted the spraying effect on weeds.

[0033] The statistical results are as follows:

[0034] group Strain control effect (%) test group 94 Control group 1 83 Control group 2 76

[0035] The above experimental results show that the compound preparation proposed by the present invention has a good synergistic effect compared with the effect of a single agent.

Abstract

The invention discloses a method for removing a weed of a Manila sward. The method comprises the following steps of mixing 20wt% of fluroxypyr and 56wt% of 2-methyl-4-chlorophenoxyacetic acid powder with water for preparing, and then applying an obtained mixture to the Manila sward, wherein the mass ratio of the 20wt% of fluroxypyr to the 56wt% of 2-methyl-4-chlorophenoxyacetic acid powder to the water is 4: (2 to 3) to 4,000. Compared with a single agent, a compound preparation provided by the method for removing the weed of the Manila sward has a favorable synergistic effect.

Description

technical field [0001] The present invention relates to the landscaping field, in particular to a method for weed removal in Manila turf. Background technique [0002] Manila lawns will develop a large number of weeds in the first year after planting. It not only competes with the lawn for nutrients, but also serves as an intermediate host for pests. If it is not controlled in time, it will seriously affect the growth of lawn. [0003] At present, there is no means that can completely replace the effect of chemical agents. However, there are certain defects in the control of weeds by a single chemical agent, and the control effect is not thorough enough. Contents of the invention [0004] In order to solve the problems mentioned in the background technology, the present invention proposes a compound preparation, which has a good synergistic effect, and the present invention is realized by the following means: [0005] A method for weeding Manila turf, comprising mixing...
