Looking at the smooth, sturdy rice growing up in the fields of Ut Hoai, many far-away farmers to visit and appraise him with curious question: "Have you use Gie spider spraying during period of 35 -40 days?". Ut Hoai confesses: "This season, the pressure on bugs is rather light over the whole area, so I just sprayed pesticide against Rice Leaf-folders". Hoai then explained: "Yes, if rice to be marketed goods, do not need to spray anything, but for good looking purpose, so I have to spray to preserve seed quality". During the autumn and winter 2010, rice leaf-foloders spraying took 1.62 mil Dong from him, while in the village cooperative-fields of the farmer Nguyen Hoang Be (Binh Tay), the costs are very high. With the same rice seed production, but farmer Nguyen Hoang Be (cultivation area of 3 hectares) had to spray pesticides to 3 phases. Be said: "Stals appear massly in every field so I have to process perticide at the time of blooming period". If combining two types of these drugs, he have to spend a total of 3.96 mil Dong. Thus, from comparing to the above example, Ut Hoai saved 2.34 mil Dong.
With a length of about 2,000 meters along the herringbone dyke, Ut Hoai is growing flowered plants such as Sesame, iridescent daisy, sunflower, okra, stars twinkling. Before rice sowing days, he and his wife have search seed for flowers. He said: "Does not need much care this season, but at a new plant cuttings should be maintained for good. If it's sunny, they need watered once a day in the afternoon, but if it's rainny then let them are". Development tree is also good, attracting pests, particularly for harvesting okra plants and fruits every day upto few kilograms. According to MSC. Nguyen Huu An: "An Giang province has many advantages because we have done and been experienced in growing ecology flowers in the fields so in upcoming winter-spring season, there may be many farmers to looking for flower-seeds to grow, attract pests to help guide preventing from stals. Hopefully, it will increasingly be a response to farmers to follow along with the program "A must, 5 decreases". This is technical progress, protecting the ecosystem balance field, while using less pesticide-saving production costs, improve profits for farmers and protect the environment and communitie's health. Thereby, the levels and departments should strengthen the propaganda to make the farmers towards sustainable agriculture".
Eco-tech system is designed so that the rice diversification of plants and animals, or otherwise to species in the ecosystem of rice fields are abundant. From there, create food chains and food web changes in the balance but is also known as ecosystem services. From ecosystem services, the natural enemy will attack the pests and keep populations of pests to a minimum, did not cause the loss of productivity and we do not need to handle pesticides. |
