Oilseed Rape Control Technology

The locust is commonly known as the larvae, and it is the main insect pest of Linxiang District. It occurs in the main rapeseed production areas. When the winter and spring droughts are serious, the land pests in the lack of irrigation conditions are heavier. Aphid damage mainly occurs during rapeseed bolting to maturity, and the prevention or control of the aphid will cause a certain loss of production.

First, rape locusts are suitable for warmer, drier climates, warmer spring and autumn seasons, and are most suitable for their growth and reproduction. Therefore, they are generally endangered in the late spring, early summer and autumn. The aphids are clustered on the back, shoots, buds, and flowers of rapeseed by means of nymphs or raccoons, sucking the sap of the plants with a needle-like sucking device, causing the cells to be destroyed, the growth unbalanced, and the leaves curling and shrinking toward the back. The growth is affected by the yin. In severe cases, the plants stop growing and even the whole plant wilt dies. When the locust infestation damages, a large amount of water and honeydew are discharged and dripping on the lower leaves, causing the occurrence of mycosis, which impairs the physiological functions of the leaves and reduces the accumulation of dry matter. As the migration of the host plants to migrate to seek to eat repeatedly, so you can spread a variety of plant viral diseases, causing greater damage.

Second, control methods

1. During the growing period of rapeseed, weeds are removed from the field and in the vicinity, combined with seedlings or transplanted to remove the plants. After sowing, the soil was covered with pesticide and sprayed with an insect repellent before transplanting. Timely cultivating soil and cultivating strong seedlings; intensive planting to increase ventilation and transmittance in the field.

2, yellow traps kill locusts. During the seedling stage of rapeseed, yellow plates are placed on the ground. The method is to use 0.33m2 plastic film, painted in golden yellow, and then apply a layer of Vaseline or motor oil. The frame is 0.5m above the ground and can be trapped and killed in large numbers.

3, pesticide control. In the seedling stage, there were 10% of pupa strains, the density of larvae was 1 to 2 per plant, and 10% of the twigs had an aphid at the flowering stage. Each locust had 3 to 5 aphids and spraying began. 20 grams of 10% imidacloprid, or 30% of acetamiprid EC 40-50 ml, or 50% WP 100-18, or 2.5% Kung Fu EC 10-20 ml can be used for water spray control per acre.

Hulled Hemp Seed, which is the whole seed with the crunchy outer shell removed, comes by quite a few names like Hemp Hearts, shelled Hemp Seed and hemp nut. Since the hulls of the hemp seed are quite crunchy and contain a lot of fibre, we as a society are not used to eating this kind of item.

There's no clear empirical data to suggest that Hemp Seeds make you tired and sleepy. One of the main reasons why people believe that hemp seeds may have some soporific effects is because they are high in magnesium.
