बेक-ओ-सील

फसलों को चमक, आकर्षण और प्रतिरक्षा देता है 

फायदे:

1) मिट्टी में जल प्रतिधारण में वृद्धि करता है।

2) किसी भी फसल की पूर्व-कटाई उस फसल से आने वाले फलों की चमक, आकर्षण और स्थायित्व को बढ़ाती है।

3) फसलों को प्राकृतिक सिलिकॉन की आपूर्ति हो जाती है।

4) फसलों की इम्यून सिस्टम को मजबूत करता है।

5) प्रकाश संश्लेषक गतिविधि/हरित पदार्थ के निर्माण में वृद्धि करता है।

6) फसलों को वातावरणीय परिवर्तन से प्राकृतिक सुरक्षा प्रदान करता हैं।

7) वाष्पीकरण में कमी और रस-अवशोषित करने वाले कीड़ों की रोकथाम करता है।

8) सिलिकॉन का प्राकृतिक आवरण पत्ते को एक हरी चमक और गहरा हरा रंग देता है।

खुराकः 1-2 ml प्रती एक लिटर पानी मे मिलाकर हर 15 दिनों में स्प्रे/ड्रिप करें।

बेक-ओ-सील

फायदे:

१) पाण्याच्या कमी उपलब्धतेत पिकाची तग धरुन राहण्याची क्षमता वाढते.

२) कोणत्याही पिकांच्या काढणी अगोदर वापरल्यास त्या पिकापासून येणाऱ्या फळांना चकाकी, आकर्षकपणा व टिकाऊ क्षमतेत वाढ होते.

३) पिकांना नैसर्गिक सिलीकॉनचा पुरवठा होतो.

४) पिकामध्ये रोगप्रतिकारक शक्ती वाढते.

५) प्रकाश संश्लेषण क्रिया/हरीतद्रव्य निर्मितीत वाढ होते.

६) वातावरणाच्या बदलापासून पिकांना नैसर्गिक संरक्षण मिळते.

७) बाष्पीभवन क्रियेत घट व रस शोषणाऱ्या कीटकांना आळा बसतो.

८) सिलीकॉनच्या नैसर्गिक आवरणांमुळे पानावर हिरवा गर्दपणा व चकाकी येते.

वापरण्याचे प्रमाण : १-२ मिली बेक-ओ-सिल प्रति लिटर

पाण्यात मिसळून स्प्रे/ड्रिप मधून दर १५ दिवसांनी सोडावे
