PEST

– An unwanted organisms which compete with people for food and shelter, or threatens their health, comfort or welfare.

• Insects

* Diseases

* Rodents

A combination of all farm management practices to minimize pest population to a non destructive level without a single application of synthetic pesticides (ZERO PESTICIDES APPLICATION).

Last resort to combat the pest occurrence is to utilize the botanical control

1.1. CULTURAL MANAGEMENT CULTURAL MANAGEMENT PRACTICESPRACTICES

The oldest and the cheapest methods of controlling pest which includes the agronomic practices and even the indigenous knowledge system (IKS) to reduce pest population.

Planting by phases of the moon.

B. Magical and Superstitious B. Magical and Superstitious Practices Practices

Food offering to rats in return for sparing the crops

C. Practices Effective in C. Practices Effective in Community LevelCommunity Level

1. CROP ROTATION

Rotating rice with a non host crop will remove a pest food and reverse its population build-up.

Page 22: Apm 02 final

Practices effective in Practices effective in community level…….community level…….

2. PROPER LAND PREPARATION

Kill the pupal stage of insect pest in the soil.

Buries weed seeds deep in the soil where they cannot germinate.

Page 23: Apm 02 final

Practices effective in Practices effective in community level……..community level……..

3. TRANSPLANT OLDER SEEDLING

More competitive with weeds.

Minimize golden apple snail attack

Practices effective in Practices effective in community level……community level……

4. Wider planting distance.• 30x10 cm (dry season)

• 40x10 cm ( wet season)

• ? Closer planting distance, provide better canopy cover to shade out weeds but increase Green leafhopper and brown plant hopper oviposition sites and lead to higher population and greater damage.

Page 25: Apm 02 final

Practices effective in Practices effective in community level …..community level …..

5. PLANTING ORIENTATION

• Following the EAST- WEST planting orientation.

Page 26: Apm 02 final

Practices effective in Practices effective in community level…..community level…..

6. ELIMINATION OF ALTERNATE HOST

• Remove plants (weeds) that look like rice such as grasses family

“ Echonocloa species”

• Reduce nesting sites and shelter of rats.

Page 27: Apm 02 final

Practices effective in Practices effective in community level…..community level…..

7. PROPER WATER MANAGEMENT

• Avoid too much water? Maintaining standing water in

the paddy control most weeds but encourages whorl maggot, caseworm, and brown plant and leaf hopper attack

Flooding = Drives away the green leaf hopper and the brown plant hopper.

Page 28: Apm 02 final

Practices effective in Practices effective in community level……community level……

8. STUBBLE MANAGEMENT

* Cut the crop close to the ground and spreading the plants to expose them to the sun to kill insects especially the stem borers inside the stem.

9. AVOID PLANTING IN SHADY AREA

* Cut excess tree branches, twigs of plant that surround the area.

10. PLANTING OF TWO OR MORE LINES/VARIETIES OF CROPS.

* Minimize insect pest infestation.

11. REDUCTION OF NITROGEN FERTILIZER APPLICATION.

High application of nitrogen fertilizer:

= increases weed population in the current and subsequent crops.= Increase the incidence of fungal and bacterial diseases by increasing tissue susceptibility and tiller density that favors dew formation.= Encourages the multiplication of brown plant hopper and leaf folder insects which lead to higher populations and greater damage.

2. PHYSICAL CONTROL2. PHYSICAL CONTROL

A. HAND PICKING

Collection of infested plant parts.

Collection of different stages of different insect pest

(egg-larvae-pupae-adult)

3.3. MECHANICAL MECHANICAL CONTROLCONTROL

A. SMUDGING

* Repel the adult insects only.

B. LIGHT TRAPPING

Attract the adult insectsFull moon

*green leafhopper* Brown plant hopper* Gall midge*Black bug

New moon*Cutworm*Armyworm*Stem borer* Leaf folder*Hairy caterpillar

Page 35: Apm 02 final

c. Natural insects attractant

Pheromone traps = methyl eugenol(scented chemical or compounds/substance)found in the female insects that attract the male insects whereby disrupting the insect life cycle.

Aromatic insect attractant (AIA)

Nature farming/organic farming practice in pest control

* coco toddy/coconut wine * moscovado sugar

* boiling water

4. BIOLOGICAL CONTROL

Utilization of natural enemies (predators, parasites and pathogens)

Page 37: Apm 02 final

Biological control……..

A. PREDATORS A helpful insects known as generalist

which feed on all stages of different insect pest.

Both the immature and adult stages prey upon/feed on its host.

It has a chewing and piercing sucking type of mouthparts.

Page 39: Apm 02 final

Biological control….

B. PARASITES An insects

(commonly wasp and flies) whose larvae develop within the body of its host and usually feed on a single host and destroy it gradually.

Page 40: Apm 02 final

Biological control… parasites

3 kinds of parasites1. Egg parasites An insects (wasp/flies)that destroy the eggs of the destructive

insects.Example: Trichogramma wasps Tetrastichus wasp Telenomus wasp

Page 41: Apm 02 final

Biological control…parasites

2. Larval parasites

An insects that destroy the larvae of many destructive insects.

Example: Ichneumonid wasp Braconid wasp Tachinid fly

Page 42: Apm 02 final

Biological…..Parasites

3. Pupal parasites

An insects that destroy the pupae of the destructive insects.

Example: Chalcid wasps

5. BOTANICAL PLANTS

Utilization of plants with insecticidal properties.

Either through spray application or as repellent.

Page 45: Apm 02 final

Botanical……

Example: Madre de cacao Neem tree Tobacco Lemon grass Sweet basil Marigold flowers Hot pepper Chysanthemum flower Derris

Page 46: Apm 02 final

Botanical control application…

Will only be applied in spot treatment.

Most of the botanical plants can kill the beneficial insects.

Hence, application is only recommended when the population of beneficial insects is very low upon monitoring.
