The mas snail (Pomacea canaliculata) becomes one of the most important pests that always attack rice plants in food production centers. Conch mas damage the plants by scratching the plant tissues and eating them so that the seeds are lost.
The critical time of masculine control is 10 HST (days after planting) or 20 HSS (day after seed dispersal / seed). If there is known in the rice field there are pink eggs of various sizes, it is necessary to regulate water.
The snail mas really liked the waterlogged place. The golden snail attack impacts the rice production level. One of the controls is to prevent the introduction of the golden snail on the new area. If the snail mas enter a new wrong area then the golden snail will quickly reproduce, especially on land that is always inundated with water. If it is so this pest will be difficult to control.
Coconut mas control should pay attention and apply integrated pest management (IPM) and sustainably, so even though the rice plants are large> 30 HST the control should be carried out. It aims to prevent attacks in the next season in the same area and surrounding rice fields.
Chemical pest control can also be the last alternative solution, but keep in mind that chemical pest control also has adverse and detrimental effects such as resistance, resurgence and pesticide residues. Therefore, efforts should be made to control the use of vegetable pesticides first.
Eco-friendly snail handling can be done with anthracanant / decoy plants. These plants are papaya leaves, lamtoro leaves, cassava leaves and bran. Can also use plants kangkung, but if not immediately clean the rest of the plant can be a weed in the fields. Ingredients as antraktan is very easy to obtain and environmentally friendly.
The leaves are used as antraktan is placed on each side of the rice field plot. If the farmer knows him with the term "sukon", "sukon" is usually always flooded water because of its function as a drainage on agricultural land. Conch mas will eat the leaves and then the golden snail can be collected using jarring or taken directly by hand.
From direct practice on ciherang rice varieties with age from vegetative to genaretive 18 weeks (120 days). Papaya leaves can control 25,344 heads with an average of 211.2 head / day / feed point. Leaf lamtoro can control 17,370 heads with an average of 144.75 head / day / feed point. Cassava leaves can control 16,164 tails with an average of 134.7 head / day / feed point. While the bran can control 5,490 heads with an average of 45.75 head / day / feed point.
By means of controlling terebut eat rice production can increase due to the intensity of pest become decreased. The test results proved that papaya leaf is a suitable and effective anthraktan plant.
In addition to such means, mas control snails in accordance with the principle of integrated control (IPM) can be done with the following details
a. Pratanam
The mode of control in the pretam phase is to take the snail directly and destroy it mechanically
b. Seedlings
How to control at the time of nursery is to spread more beih than usual for embroidery
c. Stadia vegetative
In the vegetative stadia can be done by planting more seeds and older age (more than 21 HSS), can also apply the pattern of planting Hazton system. Do not forget also important to make irrigation land intermittently
Sieves made of woven bamboo or can also use wire to filter sand (most of which have a green color / there is a plastic that is attached because it is more resistant to rust so durable). The filter is placed on the water entry channel to the farm, the installation must be tightly to prevent any snails entering between the sieves and the bunds.
d. Stadia generative and after harvest
Control in this phase can be done by taking it directly, and after harvest can use ducks that are grazed.
