Description

Weeding composition containing herbicide and safflower

The present invention relates to a herbicidal composition containing synergistic herbicidal effective amounts of propanil and cyhalofop, with a weight ratio of approximately 1:0.1 to 0.3. The composition is especially suitable for protecting rice and controlling unwanted weeds.

Herbicide, whose chemical name is (N-(3,4-Dichlorophenyl)propanamide)) (N-(3,4-Dichlorophenyl)propanamide), is a known broad-spectrum grass, broadleaf grass ( Dicotyledonous plants) and narrow-leaf grasses (monocotyledonous plants) contact herbicides. Herbalin belongs to the amide benzene group. Herbalin can inhibit photosynthesis of plants at the receptor site of the photosystem II, thereby controlling the growth of plants. Some planted plants such as rice are resistant to herbicide. Because rice contains a high content of arylamidase, it can catalyze the degradation of herbicides into non-phytotoxic products. Therefore, Chu Cao Ling is usually used in the cultivation of rice. Over the years, it has been discovered that the same type plants of barnyardgrass and miscanthus are resistant to herbicide. The resistance mechanism of these two isotypes of weeds shows an increase in arylamidase index activity. There are a variety of strategies to study how to combat the resistance of herbicide, one of which is the interaction of herbicide with other herbicides and chemicals. One strategy suggests the use of a combination of herbicide and sapphire.

Sevograss, the chemical name is ((R)-2-[4-(4-cyano-2-fluorophenoxy)phenoxy]-propionic acid), it belongs to acetyl-CoA carboxylase ( The herbicide category of ACC enzyme) inhibitors can effectively control weeds. ACC enzyme inhibitors can inhibit the ACC enzyme, the enzyme that catalyzes the first step in fatty acid synthesis A critical step. Inhibiting the synthesis of fatty acids is speculated to inhibit the production of phospholipids, which are used to build new cell membranes needed for cell growth. Broadleaf plants are naturally resistant to the herbicide due to their insensitive ACC enzyme. Therefore, the advantages of using ACC enzyme inhibitors are based on their ability to effectively control the growth of weeds, but have no effect on the growth of broadleaf grasses.

Recent studies have pointed out a herbicidal composition containing both herbicide and sapphire. For example, US Patent No. 7,560,416 describes a composition comprising a herbicide-based product and at least one ACC enzyme inhibitor such as cyprofen. The weight ratio range of the herbicide based on herbicide to sapphire is indicated as 1:0.009 to 1:0.04. When applying a composition containing a herbicide-based herbicide and an ACC enzyme inhibitor to rice, studies have shown that compared with a traditional composition that does not contain an ACC enzyme inhibitor, the amount of herbicide-based herbicide used can be reduced by 20% , It can promote the activity of weeding.

U.S. Patent 7,846,873 also describes a herbicidal composition comprising a herbicide-based product and at least one ACC enzyme inhibitor such as sapphire, in a weight ratio of 1:0.009 to 0.04. The result of this patent is exactly the same as that of US Patent 7,560,416, that is, the two herbicidal compositions have an enhanced effect at the disclosed weight ratio.

The composition containing herbicide and sapphire described in the prior art can effectively control barnyardgrass (Barnyardgrass) (also known as barnyardgrass (or barnyardgrass)), barnyard millet, and Japanese millet (Japanese millet). ), aquatic plants and common barnyard grass. Barnyardgrass will reduce the yield of crops and because barnyardgrass absorb up to 80% of the available nitrogen in the soil, resulting in insufficient grain crops, it is recognized as one of the most harmful weeds in the world. However, the above-mentioned composition still cannot effectively reduce the growth of weeds.

Therefore, there are still effective herbicidal compositions that fail to meet the demand, especially herbicidal compositions for rice cultivation, to slow down the growth of weeds such as barnyard grass, but are essentially harmless to the crop itself. Things.
