Description

one

The invention relates to the protection of plants from adverse effects,

Known methods of protection of cultivated plants from aggressive herbicides using antidotes-acylidene nitrophthalic acid l and 5- (o1.-hydroxy-p-trichloroethyl) -8-oxyquinoline 2.

The antidote is applied together with the herbicide, either before or after application or at the same time as the seed.

The aim of the invention is to increase the effectiveness of protection of cultivated plants from aggressive herbicides.

This goal is achieved by the fact that as a antidote, compounds of the general formula are used:

Ri-co-d-cif

and

1G-0-C1

where RJ means NgM-co-UN, NH,; ,,

( or

9- or ammonium, which may be substituted by alkyl, and the consumption of the antidote is from 1.2 to 5 g per 1 kg of seeds or from 2 to 10 kg / ha when the antidote is applied

in the habitat of the plants or on the plants themselves.

The proposed oximes are used in various forms.

1. Seed dressing The active substance is used in

as wetting powder (dry dressing), concentrated .p. emulsions (wet dressing), solution (by dipping into a solution with a concentration of 50-3200 g / ml for 1-72 h.

2. Introduction to the soil before or after sowing.

15 3. Introduction of the antidote to the sowing furrow before sowing, during the sowing season or after sowing.

4. The introduction of antidote deposited on a carrier. 20 5. in the form of finished products.

The following proposed compounds have been tested (see table).

Evaluation was performed by g-point. 25, a score of 1 means complete damage to a plant, and a score of 9 means an intact plant.

As herbicides used 30 s-triazine, H - (1-methyl-2-methoxyethyl) 8802424

-M-chloroacetyl-2-ethyl-6-methylaniline The table shows that the proposed and N-pro-QQC-ethyl-N-chloro-acetyl-2, b-di-compounds change the damage to the plant ethylaniline of plants on average by 3 points.
