preparation Embodiment

[0021] In the preparation embodiment of the present invention, the number of Paecilomyces lilacinus is 500 million live spores / g granule.

[0022] 1, embodiment 1: the granule containing Paecilomyces lilacinus and tioxazafen is composed as follows:

[0023] Tioxazafen 60%

[0024] Paecilomyces lilacinus 3%

[0025] Cornstarch 6%

[0026] White sugar 3%

[0027] Silica 5%

[0028] Xanthan Gum 0.6%

[0029] Kaolin balance

[0030] The preparation method of the granule is as follows: add kaolin, Paecilomyces lilacinus, Tioxazafen, white sugar, white carbon black, cornstarch and xanthan gum into the mixing tank according to the above formula and mix. After mixing evenly, enter the jet mill for jet milling. Collect the mixed powder after jet milling into a kneader, add 13% water of the total mixed powder and knead, after kneading is completed, enter the extrusion granulator for granulation, and then enter the fluidized bed dryer for drying. Finally, the granules containing ...

Abstract

The invention provides a nematode killing composition containing main effective components namely tioxazafen and paecilomyces lilacinus. The ratio of tioxazafen to paecilomyces lilacinus is in a range of 100:1-1:6. The active components can generate a prominent synergistic effect in the abovementioned ratio range. The using amount of effective components can be reduced, and the control effect is improved. The nematode killing composition can be made into any dosage form such as missible oil, granules, emulsion in water, suspending agents, microcapsule suspending agents, suspended seed coating, and the like, and is widely used to control multiple crop root knot nematode diseases caused by pathogenic nematodes.

Description

technical field [0001] The invention belongs to the field of pesticide compositions, and specifically relates to a nematicide composition containing tioxazafen and Paecilomyces lilacinus and application thereof. Background technique [0002] Root-knot nematodes mainly harm the roots of various vegetables, showing that the lateral roots and fibrous roots increase more than normal, and form spherical or conical white nodules of different sizes on the fibrous roots of young roots, some of which are bead-shaped. The aboveground parts of the damaged plants grow short and slow, with abnormal leaf color, few fruits, low yield, and even premature death of the plants. The nematodes currently known to harm vegetables mainly include root-knot nematode high pedicle, root-knot nematode peanut, root-knot nematode northern and root-knot nematode southern. Nematodes have a wide range of hosts, often harming melons, solanaceous fruits, beans, radishes, lettuce, cabbage and other vegetables,...
