Plant Issues

American Bollworm

American Bollworm American bollworm has been identified to attack more than 180 host plants. These host plants include beans, maize, tomato, legumes etc. It has caused so much damage to the fields and has developed resistance to so many insectides that it has been popularly given the name of a global pest. In the moth phase they are brownish yellow in color with a black spot on the fore wings and a broad black patch on the margin of the hind wing. Larvae are green when they are young and their color varies when the larvae grows in size. The eggs are laid only singly on the leaves and are white in color. They hatch in a time span of 3 to 4 days. The new larvae feed on the leaves after hatching and attach the near by bolls by keeping half of the body inside the bolls and half of its body outside. The larval period is of around 25 days long whereas the pupal period is around 10 days long.  Some of the damage symptoms are as follows: The squares which are affected by the American bollworm shows flaring up with its brackets spread out. Holes can be seen on the squares by the internal tissues which are being fed by the larval and hollowed by it. We will keep posting about any such informative information on to our blogs, to help as many people as possible.

Spotted Bollworm

Spotted bollworm larvae mainly attack bolls, but also feed on squares, shoots and flowers if bolls are not present. If infested during the vegetative state, the caterpillars feed through the terminal buds of the shoots and move downward.

Black Citrus Aphid

Black Citrus Aphid affect all citrus trees in all growth stages. The aphids have long piercing mouthparts which they use to suck the sap on shoot tips and young leaves, which leads to distortions of twigs and inflorescences and the curling, rolling or folding of leaves.

Bitter Rot

Its primary symptoms appear during the spring as small grey or brown flecks on young fruits.

As soon as summer starts, these flecks have developed into small, sunken, brown lesions, sometimes surrounded by a conspicuous red halo.

Hairy Caterpillars

In the early stage of hairy caterpillars have long white hairs coming from the flanks of their body. Their main feed is leaves of mango trees in groups and several other tree species.

Aphids

Aphids basically belong to Aphidoidea Family. They are small sap-sucking  insects like greenfly and blackfly.  However, they are not harmful to crops in early stage or in small or moderate numbers. Aphid’s infest severe damage to leaves and shoots and also causes damage to plant growth.

Alternaria Blight

The symptoms of Alternaria blight usually occur in summer and are depicted by the presence of angular or circular spots of around 4 to 7 mm in diameter. In some bad cases, the spot become 3 cm in diameter.

Angular Leaf Spot

Angular Leaf Spots are very easy to distinguish since the plants suffering from this develop leaf spots that follow leaf veins. It is caused by bacteria such as Pseudomonas syringae (cucurbits) and Xanthomonas fragariae (strawberries) that survive in seeds and plant debris.
