Tornado

Introduction

Tornado Herbicide (Quizalofop ethyl 7.5% + Imazethapyr 15% EC) is a broad-spectrum herbicide formulated as an emulsifiable concentrate (EC) containing a combination of quizalofop ethyl and imazethapyr. Quizalofop ethyl is an inhibitor of acetyl-CoA carboxylase (ACCase), while imazethapyr is an inhibitor of protoporphyrinogen oxidase (PPO). By disrupting these essential metabolic processes in plants, Tornado Herbicide effectively controls a wide range of annual grasses and broadleaf weeds in various crop and non-crop applications.

Active Ingredients and Mode of Action

Tornado Herbicide contains two active ingredients: quizalofop ethyl and imazethapyr.

Quizalofop ethyl: This active ingredient inhibits ACCase, an enzyme involved in the biosynthesis of fatty acids in plants. Fatty acids are essential for membrane formation, energy production, and other cellular processes. By inhibiting ACCase, quizalofop ethyl disrupts fatty acid synthesis, leading to chlorosis (yellowing) and necrosis (tissue death) of plant tissues, eventually leading to plant death.
Imazetypyr: This active ingredient inhibits PPO, an enzyme involved in the biosynthesis of chlorophyll and heme in plants. Chlorophyll is essential for photosynthesis, while heme is a component of cytochrome P450 enzymes, which are involved in various cellular processes. By inhibiting PPO, imazethapyr disrupts chlorophyll and heme synthesis, leading to chlorosis (yellowing) and growth inhibition in plants, eventually leading to plant death.

Crop Applications

Tornado Herbicide is widely used on a variety of crops, including:

Legumes: Soybean, groundnut, cowpea, mung bean, black gram
Oilseeds: Sunflower, castor, mustard
Cereals: Rice, wheat, barley
Sugarcane: Sugarcane
Potato: Potato

Application Methods

Tornado Herbicide can be applied as a pre-emergence or early post-emergence herbicide, either as a foliar spray or a soil drench.

Pre-emergence application: Apply the herbicide before the emergence of weeds, typically within 2-3 days after planting or transplanting.
Early post-emergence application: Apply the herbicide when weeds are small and actively growing, typically within 7-10 days after emergence.
Foliar spray: Mix the recommended dosage of Tornado Herbicide with water and apply it to the leaves of weeds until they are thoroughly wet.
Soil drench: Mix the recommended dosage of Tornado Herbicide with water and apply it to the soil around the base of crop plants or non-crop areas.

Dosage Rates

The recommended dosage rate of Tornado Herbicide varies depending on the target weed, crop, soil type, and application method. Consult the product label for specific dosage instructions.

Precautions

When handling and applying Tornado Herbicide, follow these precautionary measures to ensure safety:

Wear protective clothing, including gloves, goggles, and a respirator.
Avoid contact with skin and eyes.
Do not apply the herbicide in windy conditions.
Wash hands thoroughly after handling the product.
Dispose of empty containers responsibly.
Avoid using near water sources or aquatic habitats.
Do not use on bees or other beneficial insects.

Storage and Shelf Life

Store Tornado Herbicide in a cool, dry place, away from direct sunlight and heat. When stored properly, the product has a shelf life of two years.

Conclusion

Tornado Herbicide (Quizalofop ethyl 7.5% + Imazethapyr 15% EC) is a versatile and effective herbicide that provides pre-emergence and early post-emergence control of a wide range of annual grasses and broadleaf weeds in various crop and non-crop applications. Its broad spectrum of activity, residual activity, and favorable environmental profile make it a valuable tool for integrated pest management (IPM) programs. However, it is important to use Tornado Herbicide responsibly and in accordance with label instructions to minimize potential risks to human health and the environment.
