GRANULES CONTAINING FILAMENTARY FUNGI AND METHOD OF PREPARATION THEREOF
In a method for preparing granules containing filamentary fungi, a filamentary fungi culture is mixed with at least one modified starch and a starchy flour, then fillers and possible nutrients are added to the obtained product, obtaining a paste that is subsequently subjected to granulation and drying.
1 . A process for preparing granules containing filamentary fungi, comprising:
a) mixing a filamentary fungi culture with at least one modified starch and a starchy flour;
b) adding fillers and possible nutrients to the product of a), obtaining a paste that is subsequently subjected to granulation and drying.
2 . The process according to claim 1 , where the filamentary fungus belongs to the Moniliales family.
3 . The process according to claim 1 , where the culture medium contains at least one source of carbon and/or nitrogen.
4 . The process according to claim 1 , where the modified starch is Cleargum and the starchy flour is a corn flour.
5 . The process according to claim 1 , where the modified starch and the starchy flour are present in ratios by weight comprised between 30:70 and 60:40.
6 . The process according to claim 1 , where the filler added in step b) is diatomaceous earth, and the possible nutrients are selected from among one or more flours and sugars.
7 . The process according to claim 1 , where in step b) the mixture obtained in a) is added with a mixture of fillers and flours in ratios by weight variable between 30:70 and 50:50, and optionally sugars, obtaining a paste with moisture comprised between 30 and 60%.
8 . The process according to claim 1 , where the granules obtained in step b) are dried up to a moisture percentage lower than 13%.
9 . A granular product comprising one or more filamentary fungi, at least one modified starch, at least one starchy flour, suitable fillers and possible nutrients.
10 . The granular product according to claim 9 , where the modified starch is Cleargum, the starchy flour is corn flour and the filler is diatomaceous earth and the possible nutrients are represented by sugars.
11 . The granular product according to claim 9 , where the filamentary fungus belongs to the Moniliales family.
12 . A granular product obtained by the process described in claim 1 .
13 . A esticide composition comprising the product described in claim 9 .
14 . A method for treating a substrate infested by nematodes or other parasites sensitive to filamentary fungi comprising applying a granular product or composition according to claim 9 to the substrate.
15 . The method according to claim 14 , where the product or composition is dispersed in a liquid medium and administered on the substrate by spraying.
16 . The process according to claim 2 , where the filamentary fungus is Arthrobotrys conoides Dreschsler.
17 . The process according to claim 3 , where the at least one source of carbon and/or nitrogen is selected from the group consisting of malt extract, yeast extract, molasses, sucrose, and corn steep liquor.
18 . The process according to claim 7 , wherein the obtained paste has a moisture content comprised between 35 and 55%.
19 . The process according to claim 8 , where the granules obtained in step b) are dried to a moisture percentage comprised between 9 and 10%.
20 . The granular product according to claim 11 , where the filamentary fungus is Arthrobotrys conoides Dreschsler.
