Introduction of some bio pesticide
• Matrine• Oligo sacchrin• Bioflavonoid Complex
Matrine
Matrine
• Matrine is a kind of alkaloid extracted from Sophora flavescens Ait. It can act as pestidide, fungicide and also stimulating plant growth and used for controlling the pests of Lepidoptera , mites ,etc.
Application of popular Chinese Bio pesticide
Activities and features of Sophora flavescens Ait extract
1. Insecticidal activity contact poison firstly, stomach
poison secondly. It can control and kill pests.
2. Bactericidal activityIt can inhabit fungus, bacterium and
virus.
3. Stimulate plant growth Amino acids, fatty acids and other
substances in it can stimulate and regulate the growth of crops.
Application of popular Chinese Bio pesticide
Field trial collection of Matrine product• To control mites on citrus(0.5% matrine)• To control aphides on rose(0.3% matrine)
Application of popular Chinese Bio pesticide

2.To control aphides on rosesTest Condition
• Test place: an indoor laboratory of Bogota City in Colombia • Test period: August 2006
Test design• Treatment: 0.3% matrine 1000 times(1kg/ha), 20% methomyl
1500 times(0.75kg/ha) and water control• Application times: one application for each treatment Efficacy calculation We check the pests alive and dead number after 1 days, 3
days, 7 days and 10 days. For each check, we chose 10 plants randomly and for each plant we checked 10 leaves.

Use of Oligo saccharin at the beet crop
Objective: To evaluate performance in the control of nematode
• Products used: 3% Oligo saccharin x Nemix(nematocide) x Control • Technical Responsible: Ricardo Martins• Property: Farm Canada• City: Uberaba, State of Minas Gerais• Producer: Claudio Carvalho Ottoni• Date of installation of test: 18/12/2008 Pontecial of the producer:
• Carrot 650 ha to 700 ha / year• Beet 120 ha / year
Culture: • Variety: Beet Ferry Morse : Ferry Morse• Destination of output: Fresh Consumption
Date of sowing / transplanting: 18 / 12 / 08 Date of collection: 08 / 03 / 08• Planting spacing: plots has a width of 1.75 m with 4 double rows, where we have
20 plants in double line, obtaining a final stand of 457,000 plants / ha.
Technique of cultivation: Irrigation Central Pivot. Methodology: The trial was to test an area of 1,000 m2 and the control is
in the central area.
The applications were as follows:– 1st application 03 days after sowing; – 2nd application 07 days after germination; – 3rd application 20 days after germination; – 4th application 40 days after germination; – 5th application 60 days after germination.
• All applications were isolated, because we do not know the compatibility, and used for all applications a flow of 400lts of water / ha with a dosage of 800ml/ha.
• Valuation:
• - 1st Rating: 19/01 - after thinning - 2nd Rating: 17/02

Overview of rose plantation Application of popular Chinese Bio pesticide
When the buds of rose infected by powdery mildew, they would not open or even they will not come into flower.
Application of popular Chinese Bio pesticide
New leaves sprouted after applied with 15% Bioflavonoid Complex. After recovery, the white powder was removed, there were yellow spot on the leaves.
