Problems solved by technology

There are many disadvantages to using the above herbicides to control ground shoots
For example, these herbicides have a poor worker safety rating (their toxicity is T / T+), they are slow to act, require high application rates, and sometimes cause wounds that allow disease to enter
[0006] Apparently, chemical treatments to control harmful ground shoots with herbicides currently in use are flawed

Embodiment 1

[0032] Efficacy test of carfentrazone-contrane on harmful ground branches of vines

[0033] The test was carried out as follows: 12-36 g / hl of carfentrazone formulated as 60ME (equivalent to 0.2-0.6 l / hl of SPOTLIGHT PLUS 60ME containing 60 g / l of carfentrazone in the composition) was sprayed on vine branches. Lianas were evaluated periodically after application. The percent control or efficacy (%) was determined as the percent reduction in volume of vine shoots after spraying compared to the untreated reference. 4 trials were performed.

[0034] The results are shown as the mean of 4 trials, compared to those observed in the same trials with 1.0 l / hl diquat (Reglone 2) and 1.4 l / hl paraquat (Gramoxone Plus). Results and comparisons are shown in Table 1 below.

[0035] ratio

[0036] DAT = days after treatment

Embodiment 2

[0038] Efficacy of a second application of carfentrazone on harmful ground shoots of vines

[0039] The test was carried out as follows: 12-18 g / hl of carfentrazone formulated as 60ME (equivalent to 0.2-0.3 l / hl of SPOTLIGHT PLUS 60ME containing 60 g / l of carfentrazone) was sprayed on vine branches. A second application was given 30 days later. Lianas were evaluated periodically after the second spraying. The percent control or efficacy (%) was determined as the percent reduction in volume of vine shoots after spraying compared to the untreated reference. 4 trials were performed.

[0040] Results are shown as the mean of 4 trials, as observed in the same trials with 2 x 1.0 l / hl diquat (Reglone 2) and 2 x 1.4 l / hl paraquat (Gramoxone Plus) at 30 day intervals compare the results. Results and comparisons are shown in Table 2 below.

[0041] ratio

[0042] DAST = days since second treatment

Embodiment 3

[0044] Efficacy test of carfentrazone on harmful ground branches of plum tree

[0045] The test was carried out as follows: 12-27 g / hl of carfentrazone formulated as 60ME (equivalent to 0.2-0.45 l / hl of SPOTLIGHT PLUS 60ME containing 60 g / l of carfentrazone) was sprayed on ground branches of plum trees. Plum trees were evaluated periodically after application. The percent control or efficacy (%) was determined as the percent volume reduction of ground shoots after spraying compared to the untreated reference. Three trials were performed.

[0046] The results are shown as the mean of 3 experiments, compared to the results observed in the same experiment with 1.25 l / hl gluphosinate (BastaF1). Results and comparisons are shown in Table 3 below.

Abstract

Protoprophyrinogen oxidase enzyme-inhibiting herbicides are useful in a method for controlling unwanted ground shoots of vines and other trunk vegetation. Of particular interest is the use of carfentrazone ethyl and certain metabolites thereof for control of unwanted ground shoots of vines and other trunk vegetation.

Description

[0001] This application claims priority to US Provisional Application No. 60 / 543,348, filed February 10,2004. field of invention [0002] This invention relates to the field of unwanted ground shoot control of vines and other trunk plants. Background of the invention [0003] Noxious ground shoots grow at the base of the trunks of vines and other tree-stemmed plants, where they suck nutrients and impede trunk growth. For a strong, healthy trunk, harmful ground shoots must be removed. Physical removal, chemical treatment, or a combination thereof are often used to control these noxious ground shoots. [0004] Physical removal is expensive and time-consuming. Physically removing ground shoots can actually cause wounds in the trunks of vines or other tree-stemmed plants. Exposed wounds can allow disease to enter and adversely affect the growth or death of vines or trunk plants. Therefore, physical removal is suboptimal. [0005] Chemical treatment of harmful ground shoots ...
