Insect Repellant / Insecticide General Hydroponics View available resources

General Hydroponics PREVASYN™ Insect Repellant/Insecticide has a repellant effect on soft bodied insects and mites. Increases pest vulnerability to insecticides or miticides. This product acts on contact to weaken the cuticle of some immature stages of insect and mite pests. For best preventative results, this product must be applied at least once a week on a regular and continuous basis. The repellant effect of this product protects the crops from pest population establishment by its anti-feedant and anti-egg laying properties.

Available sizes

This product is a repellant and insecticide formulated using concentrated plant extracts that can be used alone as a repellant or in tank mixes with other biological or conventional insecticides or miticides to improve the level of control.

The repellant effect of this product protects the crops from pest population establishment by its antifeedant and anti-egg laying properties.The irritant effect of this product increases pest mobility, exposure and vulnerability to insecticides or miticides that act on contact. This product weakens the cuticle of some immature stages of insect and mite pests.

Use on vegetable, ornamental plants, trees, shrubs, flowers and foliage as a foliar spray to control or suppress soft bodied pests such as thrips, mites, lepidopteran larvae and mealybugs. The repellant action of the product has also proven to be effective on some weevils, thorn bugs, psyllids, leafhoppers and spittlebugs.

  • Our Pro Feedchart Usage Guide explains how to interpret and use General Hydroponics Pro Feedcharts. It is intended as a companion piece to General Hydroponics Pro feedcharts for FloraPro, Flora Series, Cocotek and Maxi Series.

  • Absolutely! All of our nutrient blends contain the necessary elements for plant growth. Start with the formula ratios identified on the label for the specific plant or crop you are growing, and then adjust and experiment until you find the right formula for your specific need.

    For further information, refer to our Drain to Waste feed charts.

  • pH is a measure of the hydronium ion H3O+. It is based on a logarithmic scale from 0 to 14. “Pure” water has a pH of 7.0. If the pH is less than 7, the solution is acid. If the pH is greater than 7 it is alkaline. Because the scale is logarithmic and not linear, a pH of 6 indicates ten times more H protons than a pH of 7, and a pH of 5 indicates 10 times more protons than a pH of 6.

  • Ventilation is often overlooked as a problem. Plants absorb nutrients when the water molecules in the leaves respire (i.e. evaporate). Better ventilation aids a high transpiration rate, which translates into a greater rate of nutrient uptake. Remember that ventilation means changing the air, not just blowing it around the room (circulation).

  • pH is important because it affects availability and absorption of several of the 16 atomic elements needed for plant growth. Maximum absorption of these elements is found at pH readings 5.5 to 6.5. When pH falls below this range many of the macro elements (N, P, K) have less availability, and absorption of the micro nutrients can reach toxic levels.

  • Water containing too much calcium and magnesium (called “total Hardness”) may create serious problems. Contact your municipal water supplier who can provide you with an analysis of your water supply. If you are using well water, many laboratories can provide you with an analysis if you send them a sample. If the dissolved salts in your water supply measure 200 ppm or more, we strongly recommend that you obtain a water analysis to determine calcium content. Excessive calcium is the main factor in determining if your water is hard. If an analysis of your water supply reveals that the Calcium content of your water supply is greater than 70 ppm (mg/liter) you should use Hardwater FloraMicro. Hardwater FloraMicro provides rapidly growing plants with a combination of chelated micro nutrients uniquely formulated for hardwater conditions. Other options are to collect rainwater, install a reverse osmosis filtration system, or use purified water. Do not use mineral or “spring” water, which can unbalance the nutrient solution, or even be toxic to plants.
