Embodiment 1

[0043] Embodiment 1, Trichoderma liquid medium formula: sugar beet liquid 0~20.0g, (NH 4 ) 2 SO 4 0~2.0g, MgSO 4 ·7H 2 O 0~0.2g, KH 2 PO 4 0~2.0g, 0~10.0g sucrose;

[0044] Biopesticide composition in paste form and preparation method thereof: the ingredients of the invention include: Trichoderma hyphae, Trichoderma chlamydospores, hydrochloric acid, potato starch and copper ions.

[0045] Adopt Trichoderma liquid culture medium formula 1: sugar beet liquid 20.0g, (NH 4 ) 2 SO 4 0g, MgSO 4 ·7H 2 O0.2g, KH 2 PO 4 2.0g, sucrose 0g;

[0046] Trichoderma was inoculated by 5% inoculum, at 26 ° C, after 36 hours of shake cultivation at 150 rpm / min, filtered, the mycelium after filtering was taken out, the pH of the mycelia was adjusted to 3.5 with hydrochloric acid, and a small amount of copper ion inhibitor was added, and then Add 10% potato starch and stir evenly to prepare the bio-pesticide in paste form. The preparation process needs to be operated under sterile c...

Embodiment 2

[0047] Example 2 is basically the same as Example 1, but inoculated into a sterile liquid medium with an inoculum size of 2%; shake cultured at 28°C for 48h, after the filtered mycelium was taken out, the pH of the mycelia was adjusted to 3.0, add a small amount of copper ion inhibitor, and then add 8% potato starch.

[0048] Trichoderma liquid medium formula is: sugar beet liquid 20.0g, (NH 4 ) 2 SO 4 0g, MgSO 4 ·7H 2 O 0.2g, KH 2 PO 4 2.0g, 0g of sucrose.

Embodiment 3

[0049]Example 3 is basically the same as Example 1, but is inoculated into a sterile liquid medium with an inoculum size of 10%; at 27° C., shake culture for 40 h, after the filtered mycelium is taken out, adjust the pH of the mycelia with hydrochloric acid To 4.0, add a small amount of copper ion inhibitor, and then add 5% potato starch.

[0050] Trichoderma liquid medium formula is: sugar beet liquid 20.0g, (NH 4 ) 2 SO 4 0g, MgSO 4 ·7H 2 O 0.2g, KH 2 PO 4 2.0g, 5.0g of sucrose.

Abstract

The invention discloses a pasty biological pesticide composite and a preparation method thereof. The biological pesticide composite comprises pesticide components and an auxiliary component. The pesticide components are biological prevention funguses. The biological pesticide composite is characterized in that the auxiliary material is starch which accounts for 5%-10% of the total weight of the composite. The biological prevention funguses refer to trichoderma, penicillium, chaetomium, cylindrocarpon, fusarium, Beauveria bassiana and / or metarhiziumanisopliae; a copper ion inhibitor, the addition amount of which is 0.001%-0.05% of the total weight of the composite, is added in the composite; in addition, hydrochloric acid, the addition amount of which is suitable for adjusting the pH valueto 3.0-4.0, is also added in the composite. The composite and biological pesticides prepared by using the method have the greatest advantages of stable product quality, long preservation time (18 months at normal temperature with high activity and 3 years in refrigeration condition); in addition, the invention has fastidious formula and advanced process, does not generate any wastewater, waste gas or waste residues, and is beneficial to environmental protection.

Description

technical field [0001] The present invention relates to a biopesticide and a preparation method thereof, especially a paste-form biopesticide composition, and the present invention will also provide a preparation method of the paste-form biopesticide composition. Background technique [0002] At present, most of the dosage forms of biological pesticides are powder, wettable powder, suspension concentrate, emulsifiable concentrate, water preparation, egg card, live insects, etc. Although they have certain control effects on diseases, insect pests and weeds, the storage time is not long enough, and the quality of the preparations is also low. Not stable enough. Contents of the invention [0003] The object of the present invention is to provide a kind of biopesticide composition of pasty dosage form and preparation method thereof, the biopesticide composition of this pasty dosage form can prevent and treat various plant diseases well, the pasty dosage form prepared by this m...
