UA22306U - Fungicidal composition "cursat r" - Google Patents

Abstract

A fungicidal composition contains an active ingredient which is cymoxanyl, copper oxychloride and an agronomically acceptable carrier.

Description

Description of the invention

The useful model concerns the fungicidal composition - "KURZAT R", which is intended for use in 2 agriculture for protection against phytophthora on potatoes and powdery mildew.

Fungicides that effectively control fungal diseases are constantly needed by gardeners growing various agricultural crops.

At the same time, diseases of agricultural crops are poorly controlled and the fungi that cause these diseases very quickly develop resistance to fungicides produced by industry. 70 Z (US patent 3954992) is a well-known fungicide cymoxanil, which is widely used to control fungal diseases on potato and tomato crops.

At the same time, the needs of agriculture to expand the range of agricultural plants on which fungicides can be effectively used are constantly growing.

Therefore, the task of a useful model is to develop such a fungicidal composition, the components of which would allow expanding the range of agricultural plants on which fungicides can be effectively used.

The task is solved by the fact that the fungicidal composition - "KURZAT R" contains the active substance, which is cymoxanil, and additionally copper oxychloride and inert substances, and the components of the composition are used in the following ratio, in 9% by weight:

Cymoxanil 4.0-4.5

Copper oxychloride 68.5-69.0

The rest is an agronomically acceptable carrier.

It is most effective to use a fungicidal composition, which is used in the following ratio, in 9% by mass: -

Cymoxanil 4.42

Copper oxychloride 68.95

The rest is an agronomically acceptable carrier. I«o)

As an agronomically acceptable carrier, a pigment, a wetting agent, a dispersing agent, and a filler are used. co

The most acceptable form when using the specified fungicidal composition is a powder that is able to disperse in water. with

Fungicidal composition - "KURZAT R" in accordance with the useful model, makes it possible to expand the range of agricultural plants that can be processed to protect against phytoflora and false powdery mildew.

Yes, the specified fungicidal composition - "KURZAT R" can be used not only for potatoes and tomatoes, but also for cucumbers. "

It is most effective to use the composition "KURZAT R" prophylactically or at an early stage of infection /-(p-) s (within 2 days after infection), before the appearance of visible symptoms on the plants. y The consumption rate of the working solution is 400-100Ol/ha. "" The specified fungicidal composition - "KURZAT R" has curative and prophylactic properties. The drug acts both when penetrating the leaves and by contact, affecting the mycelium of the pathogen in the early stages of development and stopping the germination of zoospores. Penetration of the fungicidal composition is carried out within 2 hours after treatment. If it rains earlier than after 2 hours, the effectiveness of the drug may be reduced and the treatment must be repeated. o The effectiveness of the indicated fungicidal composition - "KURZAT R" on cucumber crops is illustrated by d) example 1 below, in relation to the composition containing 9% by weight: (c) 50 Cymoxanil 4.42

F Copper oxychloride 68.95

The rest is an agronomically acceptable carrier

Agronomically acceptable carrier: c Pigment Prussian blue BU;

Wetting agent sodium isopropyl naphthalene sulfate 290;

Substance for scattering (dispersant) BU;

Kaolin filler 146395. 60

The basis of comparison is the control, that is, the absence of any treatment of cucumbers with a fungicide, and their treatment with the Arcerid fungicide.

Processing of cucumbers of the Competitor variety with a planting scheme of 70x35 cm was carried out in Merefa, Kharkiv region (Institute of vegetable and melon growing). The consumption rate of the working substance is 5O0Ol/ha. The processing results are shown in Table 1. -D-

Monte without ftu 11111111 and Arcerid, Passed 1186

The yield obtained according to the options indicated in Table 1 is indicated in Table 2. and

Example 2

The effectiveness of the indicated fungicidal composition - "KURZAT R" on potato crops of the Lugovaya variety is illustrated in relation to the fungicidal composition containing:

Cymoxanil 4.42

Copper oxychloride 68.95

Agronomically acceptable carrier of the rest

Agronomically acceptable carrier: -

Prussian blue BU pigment;

Wetting agent sodium isopropyl naphthalene sulfate 290;

Substance for scattering (dispersant) BU; (Se)

Kaolin filler 14.6396. at

The basis of comparison is the control, that is, the absence of any treatment of potatoes with a fungicide, and their treatment with the fungicide Aviksyl.

Experiments were carried out at the Institute of Potato Growing of Ukraine on plot 42 m 7 at the rate of liquid when spraying with 400 l/ha. The results are shown in Table 3. s « and I s -z

Example 3. Fungicidal composition - "KURZAT R" according to the useful model, which contains: cymoxanil 4.0

Copper oxychloride 69.0 de Agronomically acceptable carrier of the rest and ! - howl

Agronomically acceptable carrier: about 50

Prussian blue BU pigment; c Wetting agent sodium isopropyl naphthalene sulfate 290;

Substance for scattering (dispersant) BU;

Kaolin filler 15.096. c was used for processing greenhouse cucumbers of the Competitor variety at the rate of liquid when spraying 100Ol/ha.

Processing was carried out with an interval of 7 days.

As a result of treatment, the development of false powdery mildew is inhibited in plants. 60 Example 4. Fungicidal composition - "KURZAT R" according to the useful model, which contains:

Cymoxanil 4.5

Copper oxychloride 68.5

The rest is an agronomically acceptable carrier. b5

Agronomically acceptable carrier:

Prussian blue BU pigment;

Wetting agent sodium isopropyl naphthalene sulfate 295;

Substance for scattering (dispersant) BU;

Kaolin filler 15.0965 was used to process potatoes of the Lugovaya variety at the rate of liquid when spraying bOOl/ha.

Processing was carried out with an interval of 12 days. 70 As a result of treatment, the development of phytophthora was prevented in plants.

The above confirms that the fungicidal composition - "KURZAT R" according to the useful model makes it possible to expand the possibility of using the active substance, namely, cymoxanil, for such an agricultural crop as cucumbers.

In addition, the biological efficiency and yield when using a fungicidal composition, according to the useful /5 model, is higher compared to the use of a known fungicide.
