Synthesis and herbicidal activity of new oxazinone herbicides with a long‐lasting herbicidal activity against Echinochloa oryzicola

Pest Management Science, 2004
AbstractChemical modification of the herbicide 1‐[2‐(benzothiazol‐2‐yl)isopropyl]‐4‐methyl‐3‐phenyl‐5H‐pyrrolin‐2‐one (MI‐2826) has revealed a new oxazinone herbicide, 3‐[2‐(7‐chlorobenzothiazol‐2‐yl)isopropyl]‐2,3‐dihydro‐6‐methyl‐5‐phenyl‐4H‐1,3‐oxazin‐4‐one (MI‐3069), for use in paddy fields.

Prediction of herbicide activity

Weed Research, 1988
SummaryThe performance of a herbicide is influenced by a number of factors, such as temperature, humidity, weed species and stage of development of the weed. Trials in glasshouses and climatic chambers have shown that the shape of the dose‐response curve of a herbicide is dependent only on the mode of action of the herbicide. Therefore, the performance

Increased herbicidal activity of triazine herbicides by piperonyl butoxide

Phytoparasitica, 1991
Piperonyl butoxide (PB) is a known Synergist which enhances the activity of insecticides by inhibiting their biotransformation to less active products. We have evaluated the possible use of PB as a herbicide synergist using triazine herbicides in sensitive, tolerant, and resistant plants.

The structure–activity relationship in herbicidal monosubstituted sulfonylureas

Pest Management Science, 2011
Abstract BACKGROUND: The herbicide sulfonylurea (SU) belongs to one of the most important class of herbicides worldwide. It is well known for its ecofriendly, extreme low toxicity towards mammals and ultralow dosage application.

CHEMICAL CONSTITUTION AND ACTIVITY OF BIPYRIDINIUM HERBICIDES

Tetrahedron, 1968
Abstract For high herbicidal activity of the type associated with diquat and paraquat the diquaternary salts should be of compact size, stable in aqueous solution and be capable of being reduced to a stable radical cation at a potential (E0) of −0.30 to −0.50 volts by a one electron transfer which is reversible.

Herbicides with Auxin Activity

1982
Here we do not want to discuss the physiology of auxins, nor the mode of action of auxin hormones, although both aspects are nearly identical with the question for the molecular mode of action of auxin herbicides. Many reviews are mainly concerned with auxins, necessarily including auxin herbicides [1–6].

Alkylating reactivity and herbicidal activity of chloroacetamides

Pest Management Science, 2003
AbstractThe relationship between S‐ and N‐alkylating reactivity and herbicidal activity within a series of chloroacetamides, including several commercial herbicides and newly synthesised analogues was studied. The S‐alkylating reactivity of selected chloroacetamides, as well as those of atrazine and chlorfenprop‐methyl, was determined by in vitro GSH ...

Herbicidal Activity of Glyphosate in Soil

Weed Science, 1982
Greenhouse studies were conducted using bentgrass (Agrostis tenuisSibth. ‘Highland′) as a bioassay species to measure herbicidal activity of 3.4 kg/ha of the isopropylamine salt of glyphosate [N-(phosphonomethyl)glycine] when applied directly to the soil surface prior to bentgrass emergence.
