How to avoid cross pollination between two varieties

Cross Pollination

Cross pollination is pollination that happens between plants, where the pollen from the male part of a plant pollinates the female flower of another plant. This process  can happen naturally or it can be induced. Cross pollination of different types of plants happens when two types of closely related plants pollinate each other, for example: Two different types of green leaf vegetables, two different types of corn, or a pumpkin plant and a squash plant. If this happens, the seed that is produced may be good, but more often the seed will be weaker than the parent plants, or may not grow at all when planted. Therefore, it is best to avoid cross pollination happening.

Here green variety zucchini cross pollinated with yellow variety zucchini.

By the same way cross pollination occurs in most of the vegetables. Some of them are pumpkin, brinjal, bottlegourd, cucumber, etc....

A few techniques for reducing the chance of different types of plants cross pollinating:

• Plant one type of crop each planting season. For example, one type of corn or one type of eggplant

• Green leaf vegetables, lettuce and cabbage flower at the end of their life. Let only one type of green vegetable, one type of lettuce, or one type of cabbage reach the stage to flower and produce seeds

• If different types of plants are further apart, and many other plants are planted in between them, the chances of cross pollination are reduced

• Hand pollination, such as of pumpkins, melons, luffa and cucumber will allow you to choose the type of seed which will be produced

Reducing Mosquito problems

Mosquitos are the major problem nowadays. On rainy season, the population of the Mosquitos increase due to various factors. The Mosquitos are one which causes dengue and transfer diseases from one person to another. The medicine for dengue is present in nature. The doctors advice to take the papaya leaves syrup at the early morning to reduce the symptoms of dengue. Here, let us discuss about a topic on how to reduce Mosquitos problems in our surroundings.

Extra water during the wet season can be stored in ponds or banana pits by using trenches and swales. This will prevent stagnant water forming on the ground, so that mosquitoes will only be able to lay their eggs inside the pond. Fish, frogs, lizards and insects that live in and around the pond will eat the mosquito eggs and larva in the water. Because of this mosquitoes will reduce in number, and hence the risk mosquito spread disease will also be reduced. These insects and small creatures will also eat some of the pests that feed on your vegetables.

Other ways of handling mosquito problems:

• Don’t leave water stagnant in open places, cover all water tanks and containers.
• Treat waste water properly.
• Keep small fish (tilapia are best) in containers of water that will be used for washing, not in water that will be used for drinking, they will eat mosquito larva.
• Keep fish in rice paddies to eat mosquito larva.
• Prune off old banana leaves regularly, because mosquitoes like to stay there.
• Add neem leaf regularly to every pond.
• For compost pits, soak a handful of neem leaves in a bucket for 2 days, then pour some liquid with the neem leaves into every compost pit. Repeat this every 3 months.
