India's first indigenously discovered insecticide molecule, Pioxaniliprole, is set for commercial launch under the brand name ‘Pioxazon’ by PI Industries Ltd during the upcoming rabi season. It is expected to benefit farmers growing rice, chili, tomato, and chickpeas.

Key Highlights

• Indigenous innovation: Pioxaniliprole is India's first insecticide molecule discovered domestically.

• Regulatory approval: It has received approval from the Central Insecticides Board and Registration Committee (CIBRC) following regulatory studies and field trials.

• Approved crops: rice, chili, tomato, and chickpea.

• Target pests: Yellow stem borer, leaf folder, fall armyworm, tobacco cutworm, fruit borer, and pod borer.

• Development investment: PI Industries reportedly invested around ₹2,000 crore and took over a decade to develop the molecule.

How Does Pioxaniliprole Work?

• Pioxaniliprole belongs to the anthranilic diamide class of insecticides. It targets ryanodine receptors (calcium-release channels) in insect muscles.

• By activating these receptors, it causes an uncontrolled release of calcium, leading to feeding cessation, muscle paralysis, and eventually the death of the target insect pests.

Significance

• Boosts self-reliance: Strengthens India's indigenous agrochemical research and development capabilities.

• Supports farmers: Offers a new crop-protection option against several damaging insect pests.

• Reduces import dependence: Indigenous innovation can strengthen domestic capabilities in advanced pesticide development.

• Promotes agricultural productivity: Effective pest management can help protect crops and reduce yield losses.

चर्चा में क्यों?

• केरल के कासरगोड जिले की आठ ग्राम पंचायतें पारंपरिक जल-संरक्षण प्रणाली ‘सुरंगम’ (Surangam) को पुनर्जीवित करने की योजना बना रही हैं।

• इसका मुख्य उद्देश्य भूजल का पुनर्भरण करना(restoration), वर्षा जल का संरक्षण करना और सूखे के समय पानी की उपलब्धता बनाए रखना है।

• इस परियोजना में केंद्रीय भूजल बोर्ड (Central Ground Water Board—CGWB) के केरल क्षेत्रीय कार्यालय के विशेषज्ञों ने सुरंगों की बहाली, संरक्षण और वैज्ञानिक रखरखाव पर संबंधित अधिकारियों के साथ चर्चा की है।

महत्त्वपूर्ण तथ्य

सुरंगम केरल की एक पारंपरिक भूमिगत जल-संग्रह प्रणाली है। इसमें लेटेराइट (Laterite) चट्टानों वाली पहाड़ियों के अंदर क्षैतिज दिशा में सुरंगें बनाई जाती हैं, जिनसे प्राकृतिक रूप से रिसने वाला भूजल(ground water) बाहर निकलता है।

सुरंगम की प्रमुख विशेषताएँ

1. क्षैतिज सुरंगें: इन्हें पहाड़ी के अंदर क्षैतिज दिशा में खोदा जाता है।

2. प्राकृतिक जल प्रवाह: भूजल के रिसाव से पानी सुरंग में प्रवेश करता है।

3. कम ऊर्जा की आवश्यकता: अनुकूल परिस्थितियों में पानी को प्राकृतिक गुरुत्व(natural gravity) के कारण बाहर लाया जा सकता है।

4. स्थानीय तकनीक: यह स्थानीय भूगर्भीय परिस्थितियों और पारंपरिक ज्ञान पर आधारित है।

5. जल संरक्षण: इससे स्थानीय समुदायों को पानी उपलब्ध कराने और जल संसाधनों का बेहतर उपयोग करने में मदद मिल सकती है।

भारत की अन्य पारंपरिक जल संरक्षण प्रणालियाँ

1. सुरंगम (Surangam): केरल: विशेषकर कासरगोड पहाड़ियों में क्षैतिज सुरंग बनाकर भूजल एकत्र करना

2. आहर-पाइन (Ahar-Pyne): बिहार:जल संग्रहण और नहरों के माध्यम से सिंचाई

3. जोहड़ (Johad):राजस्थान: वर्षा जल का संग्रहण और भूजल पुनर्भरण

4. कुल्ह (Kuhl) : हिमाचल प्रदेश: पहाड़ी जलधाराओं से पानी को खेतों तक पहुँचाना

5. जाबो (Zabo): नागालैंड: जल संरक्षण को कृषि, पशुपालन और वन संरक्षण से जोड़ना

6. बांस ड्रिप सिंचाई: मेघालय: बाँस की नलियों से पानी पहुँचाकर सिंचाई करना
