Plant Extract Controls Potato Pests

An organic pesticide developed from plant extracts has been observed to have both fungicidal and insecticidal effects on white potato in a recent research in Malaybalay City in Bukidnon.

The researchers included Carmelito R. Lipoot, Adrian A. Pahayac and Juanita Salvani of the Department of Agriculture-Northern Mindanao Integrated Agricultural Research Center (DA-NOMIARC).

The organic pesticide, Antica, is a liquid that was formulated by Gigi Zaballero, a chemical engineer based in Cebu City and founder of Ahcil Laboratories.

The researchers wanted to find out the effects of Antica on white potato diseases like bacterial wilt and blight. They also wanted to see Antica’s effects on pests attacking white potato in Bukidnon such as cutworms, aphids and whiteflies. They compared different doses of the organic pesticide with pesticides used by farmers as well as the recommendation of NOMIARC.

In the case of farmers’ practice, they used chemical fungicides and insecticides in protecting their plants from insects and diseases. In the NOMIARC system, 50 tons of chopped wild sunflower was incorporated in the soil two weeks before planting.

On the other hand, different doses of Antica were compared with the farmers’ practice and that of NOMIARC system. It was found that 30 days after planting, the plants that were sprayed with Antica at 80 ml per 16 liters of water gave zero incidence of cutworms, aphids and whiteflies. That’s significantly better than the infestation of plants that were not sprayed with any pesticide (control). At 30 days after planting, the control plants had 9 percent incidence of cutworm, 27 percent of whitelies and zero percent aphids.

In the case of the diseases bacterial wilt and leaf blight, Antica also proved to be promising. At 30 days after planting, the control plants (not sprayed with any pesticide) had 9.2 percent incidence of blight and 1.7 percent incidence of bacterial wilt. Those sprayed with Antica at the recommended rate of 80 ml per 16 liters of water had zero percent incidence of the two diseases.

The researchers conclude that the results of their study gave promising results in terms of reducing the occurrence and infestation of cutworms and whiteflies. Similarly, they said, Antica provides a promising outlook for bacterial wilt and leaf blight management in potato

  True, there's a wind farm in Ilocos Norte, but the people here are paying very, very high electricity bills especially in Laoag City. And our electric cooperative here, INEC, doesn't want to accept partial payments, and immediately collects a Php50 surcharge if the consumer pays after due date. INEC is very oppressive. The wind farm seems useless because it doesn't give any change in electricity rates. INEC, most people think, is the most oppressive company in Ilocos Norte.

  Organic is the way to go. Puro na lang kemikal pinapasok natin sa katawan natin. God has given us plants and herbs where we could get medicines without side effects

  Great product from Toyota! That would really help our elderly and sick people. I hope they make it affordable

- Analysis ni Rod Brozas: ANg Bansang Pilipinas Ngayon: Sa Pamumuno ni President Noynoy Aquino
  
  ANg Bansang Pilipinas Ngayon: Sa Pamumuno ni President Noynoy Aquino: ITO DAPAT ang pagtuunan ng Gobyerno natin. Subalit, tuloy-tuloy ang pagcollect ng taxes at pagdagdag ng bagong taxes. Kaya kung ang ibinibigay na dagdag pork barrel ay ibinigay na lang sa direct tang proyekto sa NGOs at Nagtayo na lang ang Governo ng Government Own Factory na pwedeng pagtrabahuan ng mag tao, makakatulong. Ang Mahirap, patuloy ang pag-collect ng mga taxes at dagdag taxes pero patuloy ding naghihirap ang mga tao. Ang hirap na sinasabi ay ay di makayanang dagdag bayad sa Toll, Sa Gasolina, Sa Kuryente, Sa Pagkaing Binibili, Sa Tuition Fee, Sa School Supplies, Sa Damit at sa mga pang-araw-araw na sabings na natitira. Sa kabilang banda, ang makikitaan mong namimili sa mga mamahaling establismento, may mgaelectronics na magaganda at mga damit at tsinilas na mamahalin, ay mga kamag-anak ng mga Politicians at mga Politicians mismo at ibang matatas na opisyalis ng governeno. Yan ang nagiging bahagi ng hati ng status ng bansa, lumalaki ang bilang ng naguguom-o mahirap, at kumokonte ang mga average o mga middle class. Ito ang palatandaan ang ang economy ng isang bansa ay mahina...Tama na. Palitan na. Puro Tsismis at showbiz nalang. Dapat Totoong Kapakanan ng Bansa. Pagsugpo sa Corruption vs Pagkonte na kayang mong bilhin sa halaga ng pera mo = Noynoy Adminstration!

  A Letter of Plea to the Government Dear my Philippine government, I have a letter for you. I tried my best to get your attention, asking the help of several people, knocking at the doors of the Department of Energy (DOE), Department of Environment and Natural Resources (DENR), to the Department of Science and Technology (DOST)and to the Department of Trade and Industry (DTI). I failed to get your attention. I am pleading that you give a chance for me to be heard. It is about a tree I discovered and researched on as a source of sustainable biofuel.. I spent more than two years doing research on it and have proven it to be a source of sustainable fuel for cooking, lighting and blend for gasoline engines. Already, one University, the University of Tennessee has confirmed my findings. I wrote a pamphlet on how to grow the tree, extract its oil without using any sophisticated and expensive method and how it can help as carbon sink and lessen the pressure on other trees used as firewood. I have been using the oil for quite sometime now and have demonstrated it to my trainees, some coming from abroad, and to the media (international and local). I have written several articles published in international newspapers and magazines fearful that one day, biopirates will get and own the tree. To prevent this, I have done germplasm collection and seedbanked these. I started training farmers and have organized a planters group. I have planted thousands of the trees and distributed thousands more to farmers. I have a machine fabricated to extract oil at a faster and more efficient way. If only I can be extended help, I can train more, even train technicians to be trainors and plant more. Today, I am afraid I can no longer hold on to this knowledge. Biopirates have smelled blood and they are coming in for a kill. One is very near our shores. Soon, the technology and the knowhow that goes with this tree will leave us and benefit other companies or countries. I hope it will not be to late before you respond. I need your help. Help me care and produce more of these trees and teach our people in the countryside its value so that we Filipinos can be proud to say we have our own sustainable source of energy that is grown from trees, one that does not displace food crops and people but one that can be integrated with our trees and in our forests, from which they come from, in the first place. Help me to let this tree and the technology that goes with it, stay on our shores. Not to be another victim and be added to the long list of biopirated Philippine plants and knowledge. I need your help, not for me...or anything else..but for the thousands of Filipinos out there. Thank you so much. Michael A. Bengwayan, Ph.D Director Cordillera Ecological Center

  we should not let our children rely heavily on high tech gadgets and toys even if we can afford to give them these stuff. IMHO kids that are pampered with such devices lack the analytical and decision making skills that they would need when they grow up. Yung diskarte ika nga. We should train our children and let them learn how to exist without these high tech gadgetries

  The tabletop personal computer might be at the end of its days in the United States but I don't think that would be the immediate case here in the Philippines. Just look at the myriad surplus shops selling old units -- and they're still making good business! I just wish the companies in the US or Japan just donate their old PCs that are still in good condition to our schools.

  The government should focus more on creating solutions for the garbage problem in towns and cities. Solutions like this one planned in Bataan is good and could probably be the solution we need. But I do hope that the budget allocated for this are spent accordingly and not fall into some crooked politician's pockets.
