N-oxyaryloxyphenoxy carboxylic acid amide compound with bioactivity and preparation method thereof

Abstract

The invention discloses N-oxyaryloxyphenoxy carboxylic acid amide compound with weeding and inset killing bioactivities and preparation method thereof, wherein the compound is shown as formula (I). R1 is H or C1-C3 alkyl; R2 and R3 are the same or different and are H, halogen, C1-C3 alkyl and C1-C3 halogenated alkyl; X is CH or N; R is C3-C6 chain alkenyl, C3-C6 chain alkynyl, C3-C6 halogenated chain alkenyl, C3-C6 halogenated chain alkynyl, C3-C6 cycloalkyl methyl and C3-C6 halogenated cycloalkyl methyl. The compound shown as the formula (I) in the invention has broad spectrum bioactivity, not only can be used for preventing and treating various grassy weeds and part of broad leaves but also can be used for preventing and treating various injurious insets on crops such as armyworm and plutella xylostella, certain compound has high weed and inset preventing and treating effect, and good preventing and treating effect can be obtained under in the dosage of 15-375g active ingredient / hectare.

Description

technical field The invention relates to N-oxyaryloxyphenoxycarboxamide compounds with herbicidal and insecticidal biological activities and a preparation method thereof. Background technique The control of weeds and pests is very important in the process of realizing efficient agriculture. At the same time, the control of weeds and pests is also very important in forestry, animal husbandry, sideline, fishery and public health. Although there are many weed and pest control agents on the market, due to the continuous expansion of the market, the resistance of weeds and pests, the service life of drugs and the economics of drugs and people's increasing emphasis on the environment, scientists need to continue Research, and then develop new herbicides and insecticides with high efficiency, safety, economy and different modes of action. Aryloxyphenoxycarboxylic acid compounds have significant monocotyledonous herbicidal activity, and multiple active compounds of this type have...
