AI Technical Summary

Benefits of technology

The patent describes methods for treating crop plants, seasonally, at specific stages of growth. The methods involve contacting the plants with a composition containing a chemical called cyclopropylene. The treatment can lead to increased crop yield, improved quality, and better resistance to environmental stress. The methods can be applied to a variety of crop plants, including dicots and monocots, and can involve multiple treatments during the growth cycle of the plants. The technical effects of the patent include improving crop health and yield, as well as enhancing resistance to disease and environmental stress.

Problems solved by technology

Further, plants may suffer and / or die from transplant shock when they are transplanted from one location to another location.
When plants are under such environmental stress, significant losses in quality and yield are commonly observed.

example 1

Soybean Plants

[0264]To prepare the tested composition, spray tank was filled with approximately two-thirds of the total volume of water required. The amount of Powder 1 or Powder 2 was weighed according to the rate and total volume of spray being prepared. The appropriate amount was calculated to give 1% v / v of total spray volume. Adjuvant 1 was added to the spray tank, which was agitated until the mixture turned milky white. Powder 1 or Powder 2 was added to the spray container, which was then gently (not vigorously) agitated. The remaining water was added, making sure all of the powder was wet and washed off of the sides of the tank (if any had deposited there). The spray tank was then swirled or stirred for at least two minutes (2-5 minutes) to ensure good mixing of the composition. Between 5 and 60 minutes thereafter, soybean plants were sprayed with the composition.

[0265]Flat fan nozzles were used to apply the tested composition to soybean plants, producing droplet size of 100 ...

Corn Plants

[0268]Corn of hybrid variety FR1064×LH185 was planted at 72,000 plants per hectare (ha), and treated as described in Example 1. Powder 1 was used. Treatment stage (i.e., developmental stage at which corn plants are treated with the disclosed composition), treatment amounts (grams of 1-MCP per hectare), and results were as follows. The simple measure of yield is reported as metric ton (mT) per hectare. Other measures of yield are also shown. Treatments lead to increase in yield by one or more measures.

Cotton Plants

[0269]Using methods similar to those of Example 1, cotton plants were also tested. Each treated group of cotton plants was treated either two or three times, as follows:

Abstract

A method of treating dicot seedlings comprises contacting dicot seedlings with a composition comprising at least one cyclopropene one or more times prior to transplanting the dicot seedlings. A method of treating crop plants comprises contacting crop plants one or more times with a composition comprising at least one cyclopropene while the crop plants are at a specific development stage, such as reproductive stage.
