Claims23
A dilute selective herbicidal mixture for treating a crop between emergence and flowering of the crop, comprising, per 100 liters of herbicidal mixture, from 0.25 to 1 liter of a formulation comprising from 95% to 60% by weight of a pine oil and from 5 to 40% by weight of a surface-active agent and a selective herbicidal agent.
A dilute selective herbicidal mixture for treating a crop between emergence and flowering of the crop, comprising, per 100 liters of herbicidal mixture, from 0.25 to 1 liter of a formulation comprising from 95% to 60% by weight of a terpene hydrocarbon or terpene hydrocarbon derivative from 5 to 40% by weight of a surface-active agent, and a selective herbicidal agent.
A method for increasing the efficacy of a selective herbicidal composition for a crop, comprising the steps of:
- preparing a formulation comprising an effective amount of a selective herbicidal agent, an effective amount of an emulsifier, and as an efficiency enhancer, a co-formulant which is a combination of at least 50% by weight of a terpene alcohol and up to 50% by weight of a terpene hydrocarbon;
- diluting the said formulation to form a diluted herbicidal composition comprising an effective amount of the selective herbicidal agent;
- and
- applying the said diluted formulation to the crop between emergence and flowering of the said crop.
A method for increasing the efficacy of a selective herbicidal composition for a crop, comprising the steps of:
- preparing a formulation comprising an effective amount of a selective herbicidal agent, an effective amount of an emulsifier, and as a co-formulant, a combination of 80 to 90% by weight of at least one terpene alcohol and from 10 to 20% by weight of at least one terpene hydrocarbon;
- diluting the said formulation to form a diluted herbicidal composition comprising an effective amount of the selective herbicidal agent;
- and
- applying the said diluted formulation to the crop between emergence and flowering of the said crop.
A method for increasing the efficacy of a selective herbicidal composition for a crop, comprising the steps of:
- preparing a formulation comprising an effective amount of a selective herbicidal agent, an effective amount of an emulsifier, and a co-formulant consisting of pine oil;
- diluting the said formulation to form a diluted herbicidal composition comprising an effective amount of the selective herbicidal agent;
- and
- applying the said diluted formulation to the crop between emergence and flowering of the said crop.
A method for increasing the efficacy of a selective herbicidal mixture for a crop, comprising the steps of:
- preparing a diluted herbicidal mixture of a selective herbicidal agent;
- adding to said herbicidal mixture from 0.25 liter to 1 liter per 100 liters of an adjuvant comprising a combination of (1) at least 50% by weight of at least one terpene alcohol and up to 50% by weight of at least one terpene hydrocarbon, and (2) a surface active agent;
- and
- applying the mixture thus obtained to the crop between emergence and flowering of the said crop.
