Embodiment Construction

[0029] In order to promote the understanding of the novel technical concept, reference will now be made to its preferred embodiments and specific language will be used to describe them. However, it should be understood that the scope of the novel technology is not limited thereto, and any changes, modifications, and other applications to the novel technical concept described in this application will be obvious to those skilled in the art.

[0030] Unless otherwise stated, the terms "shell" and "wall" used in this application when referring to microcapsules are used interchangeably. These terms do not necessarily mean that the given shell or wall is completely uniform or do not necessarily mean that the given shell or wall completely encapsulates any substance or component located in the corresponding microcapsule.

[0031] The term "about" refers to a range of plus or minus 20% of the index value, for example, about 1.0 includes values ​​from 0.8 to 1.2 and all values ​​within this...

Abstract

A method of formulating and using a microencapsulated insecticide with an extended field life after application of insecticidal activity. These methods include the steps of forming a microcapsule that includes at least one organophosphate insecticide and at least one non-volatile compound such as an esterified fatty acid that is at least partially surrounded by a polymer shell. These formulations can be used to control insect populations by singular or periodic applications of the microcapsule microencapsulated formulations to areas adjacent to insect populations.

Description

[0001] Cross reference to related applications [0002] This application claims the priority of U.S. Provisional Patent Application 61 / 157,197 filed on March 4, 2009, which is fully incorporated into this application by reference. Technical field [0003] The various aspects and embodiments of the present invention generally relate to formulations of microencapsulated pesticides (cicroencapsulated pesticides) that exhibit favorable biological, commercial, and / or environmental properties, including combining them Long effective period of insecticidal activity after application. Background technique [0004] Controlling insect populations is essential for modern agriculture, food storage and sanitation. At present, safe and effective encapsulated insecticide preparations play an important role in controlling insect colonies. The properties of useful encapsulated insecticide formulations include good efficacy against target pests (including good initial toxicity against target insect...
