Benefits of technology

This patented inventor describes an improved herbal pesticide with two different chemicals: Dicamba and Chlorofenapyrimidone. These compounds work together very well when used alone but they don't always works properly due to their lacked interaction. To make this combination even better, researchers added another component called Volatile Intropic Concentrates ("VICC"). Vaporized Compound I) were found effective against certain types of grasses while others like Triflexa Bufonis also acted upon them. By adding these components along with other substances such as Humectants, Spreader Agents, Lubricating Oils, Different solvents, and carriers, the mixture becomes less expensive and easier to apply over crops without causing damage.

Problems solved by technology

Technological Problem: Current methods for controlling unwanted vegetations involve applying chemical agents or other substances like dithiocyanuron compounds onto seeds during germination processes. However these techniques result in high dosage rates due to their slow action properties and potential negative effects upon sensitive cropping areas. Therefore, new formulations must overcome these issues while maintaining effective killing ability against desired species under different conditions.

Abstract

The invention discloses weeding composition as well as a use method and an application thereof. The weeding composition is prepared from two active constituents including dicamba and cloransulam-methyl as well as a volatilization inhibitor, wherein the volatilization inhibitor is prepared from fatty alcohol, grease and polyoxyethylene ether; the fast-acting property of the weeding composition becomes better obviously under synergy of the active constituents and the volatilization inhibitor; when the application amount is 60 g active constituents/hectare, the highest preventing effect of the weeding composition 7 days after application can reach 93.9% for each plant, the weed control effect can be kept for 45 days or longer, and when the application amount is 60 g active constituents/hectare, the highest preventing effect of the weeding composition 45 days after application can reach 100% for each plant.
