Biological pest control is best because it’s nature’s way

Two years ago, a researcher observed that a close relative of tropical dayflower (often known as spreading dayflower) had foliage which was blighted with a leaf spot fungus. The infested leaves have been taken into the laboratory the place the fungus was extracted and cultured till a adequate amount was produced for spraying on the spreading dayflower. By means of use of the fungal spray, vital containment of the dayflower was achieved.

Though this product isn’t but out there for business use, and it isn’t recognized whether it might be efficient on different dayflowers, it’s affordable to imagine that such products are a part of our future. Pathogenic bacteria, viruses and microscopic worms (generally known as nematodes) that feed on leaves, roots or seeds also have been introduced as biological control brokers for certain weeds.

Like each different plant that grows by leaps and bounds, tropical dayflower has constructive qualities, except for its shiny sky blue flowers and plush leaves, too. Many African tribes rely on it for remedy of burns and chilly symptoms. Additionally it is edible and, although not particularly tasty, is relied upon in tropical nations as an emergency food supply during times of famine.

One recourse to controlling tropical dayflower or, for that matter, another weed, is to plant one thing that grows shortly and deprives it of sunshine. Squash, for instance, is fairly fast growing and has giant leaves that may discourage any low growing plant from improvement.

I might dig up as a lot of your dayflower as attainable after which plant squash. As soon as the squash had leafed out, the dayflower would in all probability be discouraged from growing and, as a bonus, you’d have a nice addition to your vegetable platter. And, in fact, a consistent software of mulch, protecting a three or Four-inch layer masking the dayflower plot always, would additionally depress its progress.

Tip of the week

The following insect organic control tip comes from Craig Endler, who gardens in Santa Clarita.

“Eventually your backyard pots will break, but relatively than toss them into the trash, recycle your broken pots right into a useful critter shelter. I made items of my broken pots into lizard group condos. I layered the damaged pieces in a remote part of my yard. There is a giant open center area within the shelter with many openings and exits all through. This provides the lizards a cool protecting shelter in the summertime, and a heat place to stay in the course of the winter. The lizards reward me with consuming a number of unwanted bugs in my garden, and they’re entertaining to observe as properly.”
