How to Prevent Pests and Insects on Plants | Make Homemade Pesticide from Neem
The time between late spring and early summer is the main period of pest infestation. Now before getting to know how to prevent pests and insects on your plants, it is important to note that insects on plants can be divided into categories like sucking insects, cutting insects, and boring insects. Sucking insects include jassids, thrips, aphids, mites, and grasshoppers. Some cutting insects on plants are Chafer beetles, caterpillars, and leaf cutter bees. Boring insects include white grubs, stem borers, termites, and scale insects. As it is not possible to describe them all here, I will just give you tips to prevent pests and insects on your plants:
- Keep your garden as clean as possible.
- There should not be any dry leaves or shaded petals falling on soil, as they are the best incubating medium for various pests and insects.
- Thrips, aphids, mites, stem borers, and termites are the most serious problems that can spoil the whole garden.
- Thrips and aphids are both very minute and thrips are very difficult to detect early because of their muddy color. They attack soft new shoots and buds. Leaf curl, leaf scorch spots, and deformed flowers are main symptoms of pest infestation.
- A spray consisting of any one monocrotophos insecticide, carbaryl insecticide, or endosulfan pesticide at 2ml per liter water should be sprayed thoroughly. Mites are very small insects that are difficult to be visualized under normal vision. Lifeless appearance of plant and a dusty web-like cover can be seen with mite infestation. On a serious note, mites are capable to harm roses. To prevent mites, never allow dusts to accumulate on leaves. At first, chilled water spray for a few consecutive days should be tried if it happens. If this remedy is not successful, then you can try spraying with wettable sulfur at 3 grams per liter when temperature is below 32 degrees. When temperature is more, you can try spraying with dicofol organochlorine pesticide at 2 ml per liter.
- Sometimes, you can notice leaves and buds are cut but could not find the clue who is damaging them. For this, explore your plants in late evening with a torch and you will notice beetles cutting the leaves. You cannot see them during the day, as they hide under the soil.
- Pesticide spray as described on bottle works well for thrips but termites are very difficult to manage. For them, a spray of chlorpyrifos 5ml per liter is capable to control superficial infestation. Unless you can detect a termite source, they may prevail.
- Neem-Based Pesticides: Indian lilac or neem based pesticides combined with copper sulfate should be sprayed every 10 days. Neem pesticides are available in the market in 10000 to 50000 ppm standardized concentration. Use them as described on the literature supplied by the company.
- Any kind of pesticides bear the risk of affecting the flowers even new shoots if they are used during the day especially in summers so you must use the pesticides after sunset. Use only 2 to 3 drops of soft liquid soap per liter water.
Make Homemade Pesticide from Neem
As a household formula to control insects and pests, boil about 100 gm of crushed neem leaves and 20 gm of tobacco leaves with 1 inch cube of any bathing soap and 1 liter of water for 10 minutes. When the mixture gets cooled, apply 5 gm copper sulfate, 5 gm borax and use 100 ml with 1 liter of water to spray in the evening. If you find it difficult, use chemical pesticides but use them sparingly. When required, use for two consecutive days at a gap of 15 days.
