摘要:
1-Alkyl-4-benzoyl-5-hydroxypyrazole compounds in which the benzoyl moiety is substituted in the 2-position with a halo, alkyl, or alkoxy group, in the 4-position with an alkylsulfonyl group, and in the 3-position with an optionally substituted phenyl group, for example, 1-(1,1-dimethylethyl)-4-(2-methyl-4-methyl-sulfonyl-3-(4-methoxyphenyl)benzoyl-5-hydroxypyrazole, were prepared and found to be useful for the control of a variety of broadleaf and grassy weeds. The compounds can be applied either preemergently or postemergently and can be used to control undesirable vegetation selectively in small grain crops and turf or non-selectively.

摘要:
4-Substituted 5-polycyclylpyrimidine compounds in which the 5-substituent is polycyclic and is attached to the pyrimidine moiety through an aliphatic carbon atom, such as 5-(2,2-dimethylindan-1-yl)-4-methylthiopyrimidine, were prepared and found to possess excellent herbicidal activity. The compounds are especially useful for the control of undesirable vegetation in paddy rice.
摘要:
Ionic liquids, formed by combining a carboxylic acid herbicide with certain trialkylamines or heteroarylamines, have herbicidal activity on an acid equivalent basis at least as active as the commercially used carboxylic acid herbicide salts, but are less volatile.
摘要:
Spray drift during the application of agricultural chemicals is reduced by incorporating microencapsulated oils into the aqueous solution or mixture to be sprayed.
摘要:
The compatibility of aqueous herbicide solutions containing water soluble salts of 2,4-D and glyphosate in the presence of inorganic cations is improved by the addition of polyethylenimine or polyvinylamine crystallization inhibitors.
摘要:
The present invention concerns stable herbicidal solid compositions containing built-in adjuvant which exhibit improved herbicidal efficacy when used to control weeds in flooded rice paddies or fields.
摘要:
The mixture of certain amine salts of glyphosate and 2,4-D allows the preparation of high-strength liquid compositions containing up to greater than 450 gae/L of total active ingredient loading if the pH is adjusted to about 6.0 to about 8.0. Compositions are particularly well-suited for application to crops that are resistant or tolerant to both glyphosate and 2,4-D.
