Lesson 5.4 Control Strategies against golden snail and other information about the pest. Flashcards
True or false. The control of GAS is very essential to safeguard
yields and the income of rice farmers.
True
In 1990, how many dollars does Philippines spend for production losses and attempts to control the pest.
U$$ 425 to U$$ 1.2 billion
In appropriate and rampant use of synthetic
pesticides have caused?
Hazards to may rice
farmers
True or false.Many single control method is effective thus,
integrating control measures is recommended.
No single method
Why managing the
population of golden kuhol is important ?
To have a sustainable and environmental-friendly approach.
Is a quick method of killing the snails but
it is not environment-friendly.
Synthetic chemical(Molluscicides)
It is often toxic to non-target organisms
(aquatic animals like fish, shrimps, crabs) and can affect
biodiversity and even hazardous to health of the farmers.

(molluscicides)
Types of strategies/methods for control GAS where handpicking early morning or late afternoon; crush
or feed them to chickens /ducks.
Physical control
Ways to do physical control of
kuhol infestation:
-Handpicking early morning or late afternoon
-Installing screen in water inlets and outlets and stakes
placed as egg laying sites.
-make depressed strips
-Construct a small canal
-Herd ducks into the paddy to prey on snails and other
insects, once the water is drained.
What are methods of control which can be
integrated to be able to manage golden snail population.
Physical control
Cultural practices
Biological control
Chemical control
Type of methods to control GAS where :
1.It avoid direct seeding of rice seeds.
2.Grow more seedling than the recommended rate.
3. Plant on the ridges above the water line to attract
females to lay their eggs on these rice seedlings.
4. Raising fish inside the paddy minimizes snails
and other rice pests
5. Practice crop rotation by planting
legumes after rice.
6. When population is high, drain the
field for a couple of days to make it dry
exposing the snails to the sunlight.
7. Prepare the field evenly.
Cultural practices
Type of Gas control method where rice farming integrated with fish culture is one way of controlling
kuhol infestation.
Cultural practices
Makes use of living organism to
control pests.
Biological control
Types of biological control?
- Using natural enemies/predators
- Human beings
3.Using plants with pesticidal properties is an environment-friendly method of control instead of using
synthetic pesticides.
Types of biological control where there are many
animals that are known to feed on GAS or their eggs.
Using natural enemies/predators
Animals known to feed on GAS or their eggs.
fish, birds, rats, lizards, frogs, toads,
beetles and ants
Type of biological control where preparing exotic recipes using kuhol
as the main ingredient like the famous Escargot” is a
biocontrol method to lessen population of golden kuhol.
Human beings
Is a French dish consisting of cooked edible land snails.
Escargot
Is a French term for snails.
Escargot
Type of plants that can be used
as attractants.
Taro and papaya
These can be used as
botanicals against kuhol.
neem tree, devil weed, asyang, tubli,
makabuhay(panyawan), sambong, tobacco leaves,
calamansi, papaya and red pepper fruits
Methods of control GAS where it is quick and effective but there are risks in
using this. Because of its quick results, famers’ depended on it to solve
the problem.
synthetic molluscicide
Synthetic molluscicide is an example of what type of methods to control GAS.
Chemical control
There are two approved synthetic
molluscicide namely:
niclosamide and metaldehyde
Metaldehyde formulated by?
Novartis
Type of synthetic Molluscicides that is formulated by NOVARTIS?
Metaldehyde
Type of synthetic Molluscicides that is formulated by Cropking Chem,Inc.
Niclosamide
Recommended to be used of metaldehyde
16 to 30 tablespoons
Recommended to be used of Niclosamide
7 to 14 tablespoon / 16 liters of water
This are as active ingredients of the molluscicide.
Metaldehye and Niclosamide
To best control the snail, communities should work
together to reduce snail population in their area.
Community-based snail management
Vulnerable stages of the rice plant
(below 30 days)
or transplant 25−30 day old seedlings from low
density nursery beds.
Integrated control of golden snail based on
rice growth stages where crop specifically during land
preparation, employing the following methods are recommended.
Pre-establishment of the rice
Integrated control of golden snail based on
rice growth stages where the following can be used:
handpicking, duck pasturing, trapping, staking and destruction of
egg masses, water management, use of plant attractants, sustain
handpicking, destruction of adults and eggs.
Crop establishment
It is
recommended to use these methods: duck pasturing, dry
land preparation or eliminating water in the rice fields could
help reduce GAS population.
Post production
Rice varieties that are least preferred by the GAS ?
PSB Rc 36, 38, 40 and 65
Nutritive value of snail.
12.2g protein
Pest of the snail
could be affect human health
rat lungworm
Other recipes of GAS
Guinataang kuhol and making pizza
