Abstract
Description
Technical Field
[0004] , , ,
[0001] The present disclosure relates to methods for controlling unwanted vegetation / weeds. More particularly, the present disclosure relates to methods for controlling weeds by applying a combination / composition of herbicides at reduced dosages.
Background Art
[0002] Weeds are unwanted plants / vegetation that are harmful to agriculture and significantly affect crop yields. Farmers use various types of herbicides to control weeds. Herbicides are chemicals used to specifically control unwanted vegetation / weeds.
[0003] Integrated weed management is a method that utilizes different methods to suppress weeds in a more natural way. One such method is the chemical method for weed management, including the timing and dosage of herbicide application. The timing of herbicide application is an important factor that greatly affects the efficiency of herbicides. This is because weeds are more sensitive to herbicides at some stages, and crops can also be sensitive to herbicides at some stages. The recommended dosage (i.e., the full dosage) of herbicides is determined for maximum weed control, and the closest is about 100% control. However, it is possible to adequately control weeds and obtain the desired yield even with a dosage less than the full dosage. In some cases, the reduced dosage can result in a yield comparable to or enhanced compared to the yield obtained with full dosage application. Herbicidal application at a reduced dosage of about 25% - 40% of the recommended dosage can reduce weed density below the economic threshold and efficiently control weeds without significant crop yield loss. Therefore, it is important to understand the fact that there is no clear relationship between the dose-response correlation and the decrease in herbicide dosage and the decrease in herbicide effectiveness.
[0004] Therefore, farmers are increasingly interested in more comprehensive weed management programs that reduce weed populations over time, and in the use of reduced herbicide dosages that lower production costs. Thus, in this field, there is a need to reduce the number of herbicide applications and utilize lower herbicide dosages within the crop system while maintaining crop yields.
[0005] Purpose of this disclosure The primary objective of this disclosure is to provide a method for controlling or preventing undesirable vegetation / weeds in crops.
[0006] Another object of this disclosure is to provide a method for controlling weeds and achieving increased crop yields by reducing the number of weeds in a crop.
[0007] Another object of this disclosure is to provide a method for controlling weeds using a combination / composition of herbicides that has higher efficacy than individual herbicides.
[0008] Another object of this disclosure is to provide a method for improving plant health by applying a combination / composition of herbicides.
[0009] Another object of this disclosure is to provide a method for increasing plant yield by applying a combination / composition of herbicides.
[0010] A further object of this disclosure is to provide a method for controlling weeds, the method comprising applying a combination / composition of herbicides in a reduced dose to plants or locations where weeds are growing or are expected to grow. [Overview of the project]

The term further encompasses plant crops such as fruits. The term “plant” may further include its growth material, and may include all productive parts of a plant, such as seeds, that can be used for the propagation of the plant, and vegetative plant material such as seedlings and tubers. This includes other parts of a plant, including seeds, tubers, spores, corms, bulbs, rhizomes, basal shoots, stolons, buds, and seedlings and young plants that are transplanted after germination or after sprouting from the soil.
[0023] As used herein, the term “plant growth material” is understood to mean seeds, vegetation material, such as seedlings or tubers, roots, fruits, bulbs, rhizomes, and plant growth parts such as plants, germinating plants, and young plant parts that are transplanted after germination or emergence from the soil. These young plants may be protected before transplantation by a total or partial treatment by immersion.

When applying any herbicide at the pre-emergence stage, it prevents the establishment of germinated weed seedlings. As used herein, the term "post-emergence" refers to the time point after a seedling has emerged from the ground. When applying any herbicide at the post-emergence stage, it prevents the growth of germinated weed seedlings.

The spraying rate used was 1000 L / ha. No plant toxicity was observed in the crops. The results are summarized in Table 4.
[0093] [Table 4]
[0094] A combination of herbicides containing a reduced dose of ashram at 5 L / ha and a reduced dose of cretodym showed significant control.
[0095] Example 5: Efficacy of Ashram and Cretozyme against Goosegrass The effectiveness of combinations of herbicides containing ashram and cretodymium was evaluated based on the percentage of goosegrass control at 29 days post-application (DAA) at multiple application rates. The spray volume used was 1000 L / ha. No plant toxicity was observed in the crops. The results are summarized in Table 5.
[0096] [Table 5]
[0097] It was observed that combinations of herbicides containing reduced doses of ashram (6 L / ha, 5 L / ha, and 4 L / ha) and cretodymium (1.25 L / ha, 1 L / ha, and 0.8 L / ha) showed significant control.
Claims
