EA024384B1 - Use of complex 2-morpholylmethyl-5-methylphenol salt as pesticide against oidium in grape fruits and leaves - Google Patents

Abstract

The invention relates to the use of complex chloride salt of 2-morpholylmethyl-5-methylphenol as pesticide against oidium disease in grape fruits and leaves. Morpholylmethyl and hydroxyl groups present in molecule provide pesticide with bactericidal properties and it eliminates oidium disease in leaves and fruits of different grape varieties completely after triple spraying.

Description

The invention relates to the field of petrochemistry, specifically, the use of a complex salt of 2-morpholylmethyl-5-methylphenol in a new field as a pesticide against oidium disease in viticulture.

There is information in the literature on the use of morpholylphenols as an antioxidant of transformer oil, as a bactericide against sulfate-reducing bacteria, and as an extractant for the purification of petroleum fractions from aromatic hydrocarbons.

The synthesis of morpholylphenols and their use as an antioxidant of transformer oil was reported in [1]. The tests were carried out in comparison with the industrial additive IHP-31.

The use of morpholylphenols as a bactericide against sulfate-reducing bacteria was reported in [2].

Another literature source [3] reports on the use of morpholyl phenols as an extractant for the purification of oil fractions from aromatic hydrocarbons.

[4] reported the synthesis of L- [2-hydroxy-4 (5) -methyl- and 5- (1-methylcyclohexyl) benzyl] morpholines and their use as antioxidants in transformer oils.

Another work [5] reported the use of the zinc salt of ethylene-bis-dithiocarbomic acid against oidium disease. This product is called Sineb, a yellowish powder that is produced in Russia. Sineb is used as a 0.5-0.7% suspension. Disadvantages: Ζη-salt is very poisonous, you must be too careful when using.

Bayleton is produced by Bayer (Germany) in the form of a powder, soluble in water of 5 and 25%. Influent substance of the drug triadimefas. Funkcid for grapes and beneficial microorganisms is safe 5% aqueous solution of Bayleton powder, applied at 1.0 kg / ha. The disadvantage of the drug is its minimum duration of action.

Firm Ά8Ά Germany offers fungicide Cumulus DT [7]. Drug structure:

Name: fludioxonil [4- (2,2-difluoro-1.3-benzodiox-4-yl)] -pyrrol-3-carbonitrile-tholylflanide.

Fungicide shows preventive and therapeutic actions. The fungicide cumulus DT against oidium disease is used 6 kg / ha. Disadvantages: very toxic; use of the drug stops when 30 days are left before harvesting. In this case, the formation of signs of oidium disease is observed.

The problem is intended to be solved by using in viticulture in agriculture against the disease of oidium, formed in the fruits and leaves of grapes of the complex salt of 2-morpholylmethyl-5methylphenol.

The objective of the invention is the synthesis of 2-morpholylmethyl-5-methylphenol and its use as a pesticide against oidium disease in viticulture.

The product used - the complex salt of 2-morpholylmethyl-5-methyl-phenol - is a crystalline product and has the following physico-chemical characteristics:

The complex salt of 2-morpholylmethyl-5-methylphenol is first used in viticulture as a medicine against oidium disease formed in the leaves and fruits of grapes. The presence in the molecule of the drug of the morpholylmethyl, hydroxyl group and the bond / Ν'ΉΟι provides them with high bactericidal properties.

The use of the synthesis of the complex salt of 2-morpholyl-5-methylphenol is carried out in two stages.

In the first stage, the interaction of metacresol with formaldehyde and morpholyl synthesized 2-morpholylmethyl-5-methylphenol

Physico-chemical characteristics of the obtained 2-morpholylmethyl-5-methylphenol: T _bale = 158-160 ° C / 5 mm RT. st .; T _PL = 60 ° C; molar mass is 207.

In the second stage, morpholylphenol dissolves in benzene, hydrogen chloride (HC1) is passed through it. HC1 is obtained by the interaction of NaCl with sulfuric acid

Physico-chemical characteristics of the complex salt of morpholylphenol are given in table. one.

The complex salt of morpholylphenol has been tested by the Azerbaijan Scientific Research Institute of Viticulture and Winemaking on various grape varieties: gara shany *, ag shany **, Azeri and Tabriz. The test was carried out by a known method [7]. Spraying was carried out with a manual apparatus. Grape oidium diseases were determined before spraying and after 5-1015-20 days. The pesticide used was normal at 6 kg / ha. After 5 days of spraying, they counted and observed a decrease in the disease. Accounting after 10 days of spraying showed that the disease is returning, the effect of the pesticide is reduced. Therefore, in that norm, spraying was repeated. Again, a decrease in oidium disease was observed. After 10 days, signs of the disease were again observed. For this reason, spraying was carried out for the third time.

The dynamics of the test drug are given in table. 2.

From the table. Figure 2 shows that the proposed pesticide-complex salt of 2-morpholyl-4-methylphenol after three spraying completely eliminates the disease of oidium formed in the leaves and fruits of different grape varieties.
