淡紫拟青霉

淡紫拟青霉属于内寄生性真菌,是一些植物寄生线虫的重要天敌,能够寄生于卵,也能侵染幼虫和雌虫,可明显减轻多种作物根结线虫、胞囊线虫、茎线虫等植物线虫病的危害。

淡紫拟青霉菌对根结线虫的抑制机理是淡紫拟青霉与线虫卵囊接触后,在粘性基质中,生防菌菌丝包围整个卵,菌丝末端变粗,由于外源性代谢物和真菌几丁质酶的活动使卵壳表层破裂,随后真菌侵入并取而代之。也能分泌毒素对线虫起毒杀作用。是防治根结线虫最有前途的生防制剂。

Paecilomyces violaceus is an endoparasitic fungus, which is an important natural enemy of some plant parasitic nematodes. It can parasitize eggs, infect larvae and female worms, and can significantly reduce the harm of plant nematodes such as root-node nematodes, cystis nematodes and stem nematodes. 

The inhibitory mechanism of Paecilomyces lavuviae against root-knot nematodes is that after Paecilomyces lavuviae contact with the egg sac of Nematodes, the whole egg is surrounded by biocontrol mycelium in the viscous substrate, and the end of mycelium becomes coarse. Due to the activities of exogenous metabolites and fungal chitinase, the egg shell surface is broken, and then fungi invade and replace it. It can also secrete toxins that kill nematodes. It is the most promising biocontrol agent against root knot nematode.


Effective viable bacteria number (billion /g) ≥100

Miscellaneous bacteria rate ≤2%

Product mesh number: 200 

Water content ≤8%


【 Main components】

Paecilomyces paecilomyces and its metabolites, suitable carriers.

【 Scope of use 】

Control root knot nematodes in a variety of plants.

【Product characteristics】

Paecilomyces paecilomyces is pale purple in color. The relative parasitism rate of Paecilomyces lavuviae to the eggs of rhizozoon was as high as 92.6%. This bacteriostatic agent showed a significant and lasting effect on root knot nematode disease. It is an efficient, long - lasting, safe, pollution-free and residue - free sporoprophylaxis preparation.
