Antagonistic microorganisms, microbial activator Super LDD 3 Group of the antagonistic microorganisms which can control and inhibit soil born plant pathogens both upland and lowland area especially, roots rot disease of economic crops. They consist of Trichoderma sp. and Bacillus sp.

Antagonistic mechanism
-	Ability of nutrient competition and grower than plant pathogen. It is important for limiting disease incidence and severance.
-	Directly destruction the hyphae of plant pathogen by producing lytic enzyme to beak cell and uptake protoplasm within hyphae as nutrient source.
-	Excretion of antibiotic and toxic substance to inhibit plant pathogen. Antibiotic is microbial toxins which can poison or kill other microorganism and most microbes produce more compounds with antibiotic activity.

Raw material to microbial activator Super LDD 3 cultivation
	Compost 100 kg
	Rice bran 1 kg (or chicken manual, bat manual)
	Microbial activator Super LDD 3 1 package (25g)
Procedure to cultivate

Antagonistic mechanism population of microbial Super LDD3 are increased by observing white hyphae and green color of Trichoderma spore .mix together and keep under shading area.
Utilization and application rate
1.	Rice, field crop, vegetable and and ornamental plant: 625 kg/ha, broadcast throughout planting area or banding along the row of plant.
2.	Fruit tree: 3-6 kg/plant, placement into the hole and cover with soil or application around the bush.
3.	Seedling plot: 1-2 kg/10 m², broadcast throughout planting area.
