OFGS N4 - Coleoptera Complex
Beetle and weevil complex
Beetles have hardened forewings known as
elytra, which generally form a shield like cover over the greater part of their bodies, giving them a distinctive appearance. Both the adults and their larvae have biting and chewing mouthparts, and often both are
pests of plants. Some beetles, adults and immature, are insectivores and as such are important allies of man. The larvae of beetles take on many forms; many have six thoracic legs, while others such as those of
weevils are legless grubs. And usually have a hard, conspicuous head.
Adults overwinter in debris or in leaf litter nearby fields.
Some emerge to feed in spring while others emerge during summer. The beetles feed for a couple of weeks, then females lay eggs on and in clusters of 40-60 on undersides of leaves. Eggs hatch in 5-14 days and larvae feed for 2-5 weeks. They pupate in a case attached to the underside of a leaf, and adults emerge in about a week. Upon emergence, new adults are light of colour and soft bodied; their bodies soon darken and harden. One to four generations per year. In late summer large numbers of beetles disperse from fields.
DIRECTIONS FOR CONTROL
Foliar spray with penac N4 100% water soluble and
suitable for use in conventional liquid foliar and irrigation water applications.
Dilute 80ml to 500l of water. See your agricultural dealer for further information.
Application should take place late afternoon or at first light before sun depletes the natural moisture on foliage. Spray immediately when eggs hatch during early leaf growth. This will provide protection and give the plants a healthy start. Repeat as needed to control pests, paying attention to the life cycle of beetle or weevil in your region.
We recommend the addition of 0.1% Agricultural Wetting agent to provide fast penetration to plants and soil.
Our recommendations are believed to be effective. Since the use of this
organic blend is beyond penac and it’s retailers control, no expressed or implied guarantee as to the effects of its use can be given, nor liability taken.
As with any essential oil product, keep in a cool place, out of
sunlight, and its closure tightly sealed. Store below 25°C
