UA135757U - METHOD OF PROTECTION OF RASPBERRY PLANTS FROM GRAY ROT - Google Patents

Abstract

Method of protecting raspberry plantations from damage by gray rot (Botrytis cinerea Pers), comprising spraying plantations with biological preparation, and treatment is carried out before and after flowering, at the beginning and during ripening of berries with an interval of 7-10 days, and the next spraying is carried out the day before picking berries.

Description

The useful model belongs to the field of agriculture, namely horticulture, and can be used in the technologies of biological protection of raspberry plantations against the causative agent of gray rot.

The leading place in the system of plant protection against phytopathogens and prevention of yield reduction is occupied by chemical means.

Their disadvantage is that the use of chemical fungicides is often accompanied by negative consequences both in relation to the crop and the environment in general.

The disadvantage of this method is that the use of chemical fungicides is often accompanied by negative consequences both in relation to the crop and the environment in general.

The disadvantage of this method is that the norms for the use of the drug and the terms of treatment of raspberry plantations have not been clarified.

A useful model is Me56866. IPC AO1K 67/00. A method of protecting berries from fungal phytopathogens.

Publ. 25.01.2011, Byul.Me 2), which provides for foliar feeding of plants and spraying of berry bushes with biological preparations.

The disadvantage of this method is that it does not provide control over raspberry diseases, including gray rot.

The basis of a useful model is the task of improving the method of protecting raspberries from gray rot by treating plantations with a biological microbial preparation and choosing the timing of spraying to ensure protection of raspberry berries from damage by gray rot (Voiguii5 sipegea Regz) during short-term storage.

The task is solved by spraying raspberry bushes with a 195% aqueous solution of the drug Haupsyn, which contains two strains of bacteria Rzepdotopav5 ashygeoiasiepv, titer 2x109 CFU/ml, at the rate of 5 l/ha. It is important that the first treatment of the plants is carried out before the raspberry blooms. Then spraying plants with the same drug is carried out after flowering, at the beginning and during the ripening of berries with an interval of 7-10 days, and the next spraying is carried out no later than a day before harvesting, which is planned for short-term storage.

The method includes the rate and timing of spraying plants with an aqueous solution of the drug Haupsyn of biological origin, the mechanism of action of which is based on the antagonistic properties of the active substance of the drug in relation to the causative agent of raspberry gray rot.

The research was conducted in experimental raspberry plantations of the Institute of Horticulture of the National Academy of Sciences in 2017-2018. To protect the plantations, biological preparations Planriz and

Haupsyn with bush treatment and a variant without the use of any protection techniques (control).

As a result of the research, it was established that after processing the plantings with the biological microbial preparation Haupsyn in the specified terms, the damage of raspberry berries by gray rot in the period of short-term storage decreases and is 6.7-10.7 956, in untreated plants the spread of the disease is 15.3-33.3 95 (Table 1).

In addition, the results of the experiments showed that on each of the experimental options, an increase in yield from 115 to 132 95 was ensured in relation to the control in 2017 and, accordingly, 113-128 95 in 2018 (Table 3).

The highest, economic harvest of berries was in the variant using a 1 95% aqueous solution of the drug Haupsyn (from 348 to 399 g per stem), i.e. more than 28 95 higher than in the control.

The use of the proposed method in raspberry plantations allows to reduce the damage of berries by gray rot and significantly increase the economic yield.
