Изобретение относитс  к пестицидным составам , содержащим микрофлору дл  уничтожени  вредных организмов, а также к способам применени  пестицидов.The invention relates to pesticidal formulations containing microflora for the destruction of harmful organisms, as well as to methods of using pesticides.

Известен способ получени  устойчивых взвесей микробных культур с использованием поверхностно-активного вещества (ПАВ). В качестве ПАВ берут смесь триэтаволанинового мыла жирных кислот кащалотового жира, ланолина безводного, вазелинового масла и после ее стерилизации к ней добавл ют микробную суспензию.A known method for the preparation of stable suspensions of microbial cultures using a surfactant. As a surfactant, we take a mixture of triethanolamine soap of fatty acids of cachalotta fat, anhydrous lanolin, vaseline oil, and after it is sterilized, microbial suspension is added to it.

С целью получени  более устойчивой в воде взвеси микробных культур (в частности, культур Bacillus thuringiensis Berliner, Вас. cereus var. galleriae Isakova, Вас. dendrolimus Talalaev), предлагаетс  брать в качестве ПАВ оксиэтилпрованные ди- и триэфиры пентаэритрита и карбоновых кислот Се-Ci2, в особенности оксиэтилированпые трикапрйнаты пентаэритрита, предпочтительно в количестве 0,1-0,5 вес. % к рабочей смеси.In order to obtain a more water-resistant suspension of microbial cultures (in particular, cultures of Bacillus thuringiensis Berliner, W. cereus var. Galleriae Isakova, W. dendrolimus Talalaev), it is proposed to use hydroxyethyl diethyl and tri-esters of Pentaerythritol and carboxylic acids C-C2 as a surfactant. , in particular hydroxyethyl tricapryne pentaerythritol, preferably in an amount of 0.1-0.5 weight. % of the working mixture.

Проведено изучение оксиэтилированного трикаприната пентаэритрита, содержащего 14 гликолевых остатков, условно названного окапеном - 1, и оксиэтилированного трикаприната пентаэритрита, содержащего 26 гликолевых остатков, названного (также условно) окапеном - 2.A study was carried out of ethoxylated tricaprinate pentaerythritol containing 14 glycol residues, conventionally referred to as кап 1, and ethoxylated tricaprinate pentaerythritol containing 26 glycol residues, called (also conventionally) кап d-2.

Изучение бактерицидных свойств этих неионогенных ПАВ показало, что их 1%-ные водные растворы в смеси с водной суспензией микробной культуры, вз тых в соотношении 1:1, при экспозиции 24 час, не вызывают гибели микробов.The study of the bactericidal properties of these non-ionic surfactants showed that their 1% aqueous solutions in a mixture with an aqueous suspension of a microbial culture, taken in a 1: 1 ratio, when exposed to 24 hours, do not cause the death of microbes.

Они также не вызывают гибели личинок насекомых , в частности, комаров семейства Tendridae, вз тых в качестве тест-объектов, что свидетельствует об отсутствии у этих ПАВ лаврицидных свойств.They also do not cause the death of insect larvae, in particular, the mosquitoes of the family Tendridae, taken as test objects, which indicates the absence of lauricidal properties in these surfactants.
