Problems solved by technology

Therefore, it is difficult to control a variety of weeds with one herbicide. At the same time, long-term single use of a certain herbicide will also cause changes in the weed community. Some weeds are suppressed, while others are changed from their original non-dominant status. The rising ones are dominant species or malignant weeds. In addition, long-term single use of a certain herbicide will gradually increase the resistance of weeds
With the continuous advent of dry land herbicide varieties, non-cultivated land, forest land, mountain land and other commercial crops have also begun to use chemical weeding, but the weeds in these weeding lands are various and complex, most of which are perennial deep-rooted weeds, shrubs, Ferns, these non-purpose plants seriously damage the growth of trees and crops and affect production. It is difficult to solve weed damage with a single herbicide, and it is difficult to achieve the ideal effect of production and safe weeding

Abstract

The invention discloses a composite weed killer for arbor. The composite weed killer is applied to forest land and especially applied to weed killing of cryptomeria fortune, cedar and ginkgo seedlings. The composite weed killer consists of oxyfluorfen, haloxyfop-R-methyl, atrazine and prometryn in a certain proportion; during use, the composite weed killer is mixed with water, the proportion of various effective constituents in the weed killer according to the type of weeds in the forest, so that the composite weed killer is relatively good. The composite weed killer for arbor can be used for solving the problem that the killing effects are lowered as the resistance of the weeds to the single weed killer is strengthened, so that the grassy weeds and the broadleaf weeds are effectively killed, and therefore, the killing effects are good.

Description

technical field [0001] The invention relates to the field of agricultural herbicides, in particular to a compound herbicide for trees. Background technique [0002] At present, herbicides have been widely used in agriculture. Practical results show that various herbicides have a certain range of herbicides. Therefore, it is difficult to control a variety of weeds with one herbicide. At the same time, long-term single use of a certain herbicide will also cause changes in the weed community. Some weeds are suppressed, while others are changed from their original non-dominant status. The rising ones are dominant species or malignant weeds. In addition, long-term single use of a certain herbicide will gradually increase the resistance of weeds. With the continuous advent of dry land herbicide varieties, non-cultivated land, forest land, mountain land and other commercial crops have also begun to use chemical weeding, but the weeds in these weeding lands are various and complex...
